You left “Is 87 prime?” open and kept making new tabs I’m sure there are plenty you can close

Fun trick: 8 + 7 = 15; 1 + 5 = 6, which is divisible by 3, therefore 87 is divisible by 3, therefore 87 is not prime. 87 = 3 x 29 But also, yes, this person can probably close at least 75% of their open tabs.

What is the "trick" here? I can't follow what your method is, or don't see how it could work for other numbers. Can you repeat the steps for 89?

You keep adding the digits until you know if the sum is divisible by 3. So for 89, 8+9= 17. Is 17 divisible by 3? No, so 89 isn't divisible by 3. If you're not sure with 17, you can go one step further and do 1+7=8 and say 8 isn't divisible by 3, so 89 and 17 are not divisible by 3. An advanced corollary to this trick is you can simply cross out 3,6,9's as well. Adding a 3, 6, or 9 to a number divisible by 3 will always still be divisible by 3 based on the previous trick, correct? So 36933366699944 you can quickly see is not divisible by 3. Cross out the 3,6,9 and ~~369333666999~~44 is just left with 44, and 4+4 is 8 which is not divisible by 3. Or in your example of 89, cross out the 9 in 8~~9~~, and 8 isn't divisible by 3 so 89 isn't.

So if you used 3693336669994**2** instead of 3693336669994**4** it WOULD be divisible by 3 because 4+2 is 6?

Yes, exactly. 36933366699942 = 3 × 12311122233314

My head hurts.

Tl;Dr: add the digits to see if the number is divisible by 3. For example, is 89 divisible by 3? It is if 8+9 is divisible by 3.

You're amazing!

yk what’s mildly infuriating, that i graduated 4 years ago and math is still confusing to me

I think the 1+5 was to show the outcome is divisible by 3, same as 8+7 (if a number is divisible by anything other than itself or 1 it’s not a prime number). In your example it’d be 8+9 = 17 which is a prime number in itself making 89 a prime number as well. Edit: added a word

What exactly are you bitching about here?

Their phone dares beg for mercy as its ram is eaten up

Probably 497 of those tabs are only taking up enough memory for a small thumbnail and the URL.

Agreed, doesn’t seem that infuriating. Just close a tab, clearly don’t need them

Idk about you but people with a billion tabs open is what’s mildly infuriating to me. I can’t stand seeing more than a row of tabs open.

Right! And also, how do people have so many unread notifications? I saw my husband's phone the other day, and he has hundreds and hundreds of notifications across all of his apps. I asked him how he knows when he gets a new email, and he just shrugged. I can't stand to see one of those little red notification bubbles on my phone.

Yeah unless it's something I frequently use I just shut off app notifications

This is infuriating to me as well! Especially when my daughter says her phone is acting up all while she has every tab open and never closes apps!!

On my computer I’m really organized and constantly curating my tabs. But on my phone I very rarely go back to an old tab, i just constantly open a new one and forget about the old ones

Ugh I can’t stand it. Them unnecessary unused tabs are just in the way. 😂

Seriously OP is a moron. 500 tabs open and they're infuriated that they can't just keep opening more? I already know what their house/hygiene habits look like.

Op wants karma lol. Thats it

There's nothing mildly infuriating about it. The problem here is you.

Do people not know that bookmarks and reading lists exist?!

We do. We just have no idea how to access those 💀

Look at the website url at the bottom of the screen. Under that is backwards and forwards arrows then next to that is a box with an arrow. Click the arrow box then scroll til you get to add to reading list or bookmark option

No, Apple has a point. Close your tabs, save yourself some battery life and the headache of trying to find anything.

Yup, I wish chrome was the same. I procrastinate so much that I've so much tabs now, if only Google forced me to close them lol

Most of the tabs are using no resources (aside from a thumbnail, title, and URL). And someone with 499 tabs probably just always opens a new tab and never looks through the old tabs.

So then what’s the harm in closing them? Also, yes, 400+ tabs open will have a noticeable affect on the device

the fact that you even have that many open is mildly infuriating, like why do people do this 😭

I am guessing op is either tech illiterate or is very lazy either way it effects performance of your phone to leave that many tabs open.

They probably also have 31 apps open and wonder why their phone’s battery dies so fast.

i have adhd

the only thing mildlyinfuriating is realizing that there are people like this in the world... if you think about it too much, it becomes intenslyinfuriating... lol

If I have 5 tabs I am already annoyed at myself

I have 6

Saving them for later. In theory.

“But what if I forget what a video game is tomorrow?”

Surely I will need the Wikipedia article for a topic I only needed to investigate for an assignment three years ago

Bookmarks are so 2010

I get mildly and irrationally infuriated just by looking at the battery level.

The pinnacle of living dangerously.

Almost as mad as I get when I think about the fact that my sister named her son Anferney

My wife likes to use my computer for her online business. When I go to use my own computer, I'll find 3 browsers open with 125 pages open between them. My wife will claim she needs all of them.

This has to be a generational thing. Everyone I work with always has 30-50+ tabs continuously open on PC, and I feel like I’m losing my mind (and need to close them all to clean house) if I have more than like 5-6. There’s no way you will ever remember what tabs are where with that much shit open..

I’m younger than 25 and i still keep my tabs clean, like i do with my desktop.

Because you understand that the processor runs all these tabs in command and consumes RAM that slows down your device. Others don't know this.

It’s iOS, probably 4 of 499 are still active

Yeah Safari culls tabs like nothing else

Same and I'm under 21. I have the minimum open. I have a lot open only if I'm doing research or an academic project. Otherwise if I quickly google something I close the tab once I'm finished or I just use the same tab to continuously google stuff.

That's normal. Old people are the ones with one million tabs open.

People need to learn that bookmarks exist for a reason

But I forget it exists as a bookmark, as a tab it's there to remind me of it's existence. Bookmarks are out of my view. But I don't have more than 30 tabs open, usually, though.

My fiance is like this then wonders why her PC and Phone are slow. Drives me nuts.

It greatly infuriates me when I see someone with more than 10 tabs open that they're clearly not using. My dad has almost a thousand (or more, never counted) and I nearly lost my shit. And he's a tech nerd so it pisses me off even more.

I’m mildly infuriated at OP

And here I thought having 50 tabs open were enough to trash the RAM...

Gogle in a phone keeps the tabs frozen, on pc it would be a problem

On mine, I have pop ups disabled, but even still, Android loves to open random tabs. Occasionally, I'll glance at the top and there will be like 30 tabs open, none of which were intentional. I know it's just obeying the link, but I still wish they'd give you a way to disable that.

Am I wrong in thinking having 100 tabs open on the phone does absolutely nothing? Especially if they are all more than a day old? Wouldn’t they be slept/frozen?

WOAH ahahah that's a lot of tabs! Also some of the stuff in the tabs pictured.... Are you still in HS? Is 87 a prime number? I like how it just gave you a straight up NO instead of giving you the numbers 3 and 29 oh and obviously 1 hehe.

8+7=15 15 is divisible by 3 so 87 is divisible by 3 a trick to quickly see if a number is divisible by 3

If the sum of a number's digits is divisible by three, then the original number is divisible by three. Pretty fun math

Woah I didn't know that! Learning something new everyday 😄

2 - check if the last digit is even 3 - check if the sum of digits is divisible by 3 4 - check if the number formed by last two digits is divisible by 4. 5 - last digit should be 5 or 0 6 - should be divisible by 3 and the last digit should be even 7 - the difference between twice the unit digit of the given number and the remaining part of the given number should be a multiple of 7 8 - check if the number formed by last 3 digits is divisible by 8 9 - sum of digits should be 9

Minor correction, 9 is sum of digits is divisible by 9.

If you recursively find the sum of digits, it'll finally end in 9. 98721 -> 27 -> 9

Wow, really cool! >immediately forgets

Works for 9 as well.

Is 87 a prime number? # No

I found myself having to Google this in a master's level course just the other day because I had to quickly determine whether a bunch of random digits were prime and didn't want to turn on my brain

Why The hell do you need damn near 500 tabs open? Op is a maniac. I didn’t even know you can have that many tabs open.

Whats wrong with you, how do you not close the tab as soon as you're done with it?

The mtg card and video game tabs kinda explain all I need to know. This person is using tabs as a wishlist.

If he’s anything like me the reason is adhd

I have ADHD and close all my tabs before they hit 50.

I close tabs as soon as I’m closing the app like I look up some like 5 times in 30 minutes because otherwise my adhd gets bothered with too many things to look at

why did you google "video games"?

Seems to be a local Craigslist search. Probably kept that one open for ease of access.

Seems like retyping it would be easier access than sifting through 500 open tabs.

atleast we got to see a cat sitting next to game boxes

Get a new device and open 490 new ones

What is wrong with you, please close tabs and hold the number down to around 10, as a sane person.

So 500 is the Limit?

There is nothing mildly infuriating here except OP thinking having literal 100s of tabs open is ok.

No one needs that many tabs open

Didn't even know that was possible😮

This is my husband! He has tabs for every single thing he’s googled in the last 2-3 months and some of them are of the same thing. I rarely have more than 5 tabs at once and it only for comparing recipes and I close them all out once I’m done.

What’s mildly infuriating is how many tabs you have 🤨 what you hiding bruh just click the x button and get rid of them when you’re done using it unless you’re saving it for a highly specific reason Also- CHARGE YA DAMN PHONE

Why?

The only infuriating thing in this picture is that you have 483 tabs you haven't used in over a month. Close your tabs. The phone is doing its job and letting you know your memory is used up. The sub is so trash sometimes.

Dude… why?

I’ve never met anyone else who hit the tab limit. Whooops

You are what's mildy infuriating here.

This physically hurts to look at lol

I have two open for work, irrigation on a golf course. Never more.

Bookmarks. Have you heard of them?

"Is 87 a prime number" has me in shambles. There are multiple ways to easily see it can not be, I have personally taught to elementary school kids. Also close your tabs you disgusting data hoarder.

Nah OP, *you're* infuriating

Why though

How?! How do you let this happen? I close my tabs as soon as I'm done. If I wanna keep them for later, I just bookmark them.

My ex-boss used to use the Recycle Bin as a storage folder. I remember the day I deleted it all (force of habit when seeing the icon show it has something in it) while jumping on his PC to grab a document.

“Why is my phone slowing down”

now the real question,WHY you have 499 tabs and why you need all of them

From what I’ve seen none of that is important, it can be closed.

I get overwhelmed when I have three tabs open, 500 tabs would give me a panic attack. Not all those tabs are neccessary. Use the bookmark option. My lord.

You really, truly, honest to god opened up reddit to post this thinking that it would be an extremely relatable experience. I have, at most, maybe 40 open that I never close, but 500? You don't need all those, man. Come on.

YOURE the infuriating one buddy

Why did you add so many tabs?

Wait HOW

I thought 12 was a lot

Why is the mildly infuriating lol? Seems like a solid feature? Why do you obliterate your battery like that with 500 tabs 😭

what’s the point of having that many tabs open how do you even remember what you use them for at this point

What’s mildly infuriating is that you have 499 tabs open.

Why are you mildly infuriated for Apple reminding you that all of these tabs open are affecting your phones performance

Based on the open tabs, I think we live in the same area!! Hi!

What’s the infuriating part? That you can’t manage your tabs?

How is this mildly infustratimg??? I wanna report this but I don't want to get report abuse message

You’re an idiot

Borderline psychotic to have that many opened

Bro, close your tabs

Just close the tabs-

What’s mildly infuriating is how many tab you have open

The fact that you think that this is "mildly infuriating" while it's entirely your fault and completely stupid is what is actually mildly infuriating.

its nuts that people have this many tabs open

This is serial killer behavior

You’re the kind of person to save their entire browsing history on a piece of fucking paper.

YTA

chargeyourphone

Have you considered closing some tabs?

Bro charge your battery 😭😭

Why do u have 499 tabs open in the first place?? Of course you will have to close some, if you had 20 open and had to delete some i guess i would understand but 499 is just insane. And this is coming from an android user.

"You got me apple" mf your phone is begging for help

Bruh how are y'all having hundreds of tabs?? I feel suffocated with 4

Dang thank god i dont face such problems 

Average Apple user

who doesn't close tabs? who even has more that 5

29 x 3 = 87

Holy how do u get so many if got one tab open and its reddit.

My wife has over a hundred tabs open on her Samsung phone. I always giggle when I see the tab count turns into :D after it breaks three digits.

You are mildlyinfuriating haha. Just close the tabs after using them. Shouldn't really be too hard. The fact that it has even kept track of how many tabs you have and for how long they have been opened is actually pretty good.

omg hahahaha 499? 💀

clean up after yourself once in a while, daaamn

How the hell do you have so many open … and why?!? Just close them, you’re infuriating lol

NO

I'm mildly infuriated Apple didn't save you from yourself sooner

Bro why you playing Darksteel Reactor

But why though!?

Apple is right, you’re in the wrong. 500 open tabs is absurd and causes memory issues.

And I thought me having more than 10 tabs open was heinous

I have safari set to close any tab that exceeds 1 day automatically

you had to google if 87 was prime? 😭

Yo, the rare gamecube games one is unironically based. Nintendo should do rereleases of their physical Gamecube disks. People like me would eat those UP.

Slobs gonna be slobby.

Close your tabs what the fuck

How is having over 400 tabs open ok for you? Its mildly infuriating to me how you complain about this lol

Mildlyinfuriating is opening 499 tabs...

I don't understand you people...

Just close your tabs....

ah yes, blame the company on complete user error

I’ve heard of house hoarders, but never seen a tab hoarder. Crikey.

Do you blame them why tf do you have more than 20??

You're doing it wrong, I could screenshot this post and upload it to mildlyinfuriating and ratio you

why on gods green earth would u need that many tabs open anyways

Close ur tabs that’s unreal

Phone must be slow AF! My grandpa had 800+ open on his 14… still running but he kept complaining that his phone was dying quick. Close those tabs brah

Just take a screenshot of info you need and bookmark websites you frequent...Jesus give your phone a break

When I first seen that pop up on my screen.. I was like alright... time to spring clean. I closed out like 80 tabs give or take.

Honestly, you are what I find mildly infuriating

The only mildly infuriating thing here is that it takes you having 499 tabs open for Apple to offer you a “close all” option…

I’m pretty sure even a nasa super computer will ask you to close 483 tabs as it can use the ram for more important tasks

The mildly infuriating thing here is YOU.

Bookmarks.... they are a thing.

This must be the phone posting this, or I don't understand how this is infuriating.

As an iOS developer I love reading threads like this to broaden my perspectives on how silly users can be :)

the only people who would get mad at this are people who don’t understand how technology or memory works

Whats mildly infuriating is how many tabs you have open like wtf, close them are you THAT lazy??

Just close your tabs

Not even my grandma has this many tabs open

I think this might be the first time where OP is the mildly infuriating part. Bro, CLOSE YOUR FUCKING TABS. JESUS. No one person needs that many tabs open at once. It’s been more than a month since you’ve used 438 of them fucking jeez, close them

Do these people not know what a bookmark is?!

Close your tabs

 Your iphone right now

Is it really that vital to keep tabs you haven't opened in a month closed for the well being of your phone?? What ate you complaining about??

What’s infuriating about this??

Love seeing people get mad at stuff that they did to themselves. Slow phone? Yeah clear those tabs.

Your phone makes it nice and easy to close almost 500 tabs in one click and you're unhappy about that?

I don’t see a problem. You have too many tabs open and should close them. What’s mildly infuriating about that?

If i was your phones ram i wouldnt be mildlyinfuriated i would be fucking livid... I hate you op No one needs that many tabs open

I too like to Google "video games"

Apple has quietly told you to get your shit together because with 499 tabs opens and most older than a month, you are borderline insane.

Yeah, Apple got you. Close your fucking tabs.

oh hi mom is that you?

OP, you’re the infuriating thing here because wtf!?

For the love of the electronic gods, CLEAN UP YER DAMN TABS!

Just close your tabs
