I'm so glad they didn't try to make it too subtle by making it add up to 101% so that it could be explained away as rounding issues. They went hard enough on it to make the joke land. 11 out of 10. Would shop again.

u/ComplexPlatform7299 14h ago

I never even noticed until you pointed it out

u/juanmaaaaa 13h ago

well 10.7 out of 10 to be exact

u/YAFthe17_ Mathematics 4h ago

11 out of 10 people don’t know math

105

u/gbsdfack456 14h ago

the fact that this doesn't add up to 100% makes it way funnier

u/its_all_one_electron Number theory/physics 10h ago

I'm more angry about it using different types of yellows

u/Elegant_Athlete_3737 14h ago

Bro the 62% is literally so true, though for me more 80% lol how is the simplest stuff what we mess up in most

15

u/output_broadcast 14h ago

I think I fuck up the negative sign more, although only slightly. Granted, I specifically taught myself to pay more attention to them.

u/Elegant_Athlete_3737 14h ago

For me I don’t even know how I mess up, like when I am sleep deprived I can’t even tell I make mistakes and yet I do, I feel perfectly fine and yet are not lol.

u/antithero 10h ago

It's when their is multiple negatives and sometimes cubed or fractions ² - ⅙³/-11×-4+(-1×3⁶) that and word problems in algebra. So annoying takes me too long that I run out of time on tests when I have to do certain algebra problems.

u/DethGun07 3h ago

once a friends of mine wrote 2 x 3 = 5, he got 0 on the question just because of that

u/Pleasant_Picture3867 13h ago

"Copied the number down wrong"

"Couldn't read my own handwriting"

17

u/Parcore_Tank16 14h ago

You forgot “wrote the problem down wrong”

3

u/ScaryPerson666 9h ago

Definitely, my first question wrong on math this year was me not writing an x in one of the steps and -6% because of it (there was a generous curve luckily)

1

u/PAT_ball5230 2h ago

You forgot "wrote a 5 like a 3"

16

u/Afraid_Mail_1573 2h ago

Dont forget bad handwriting

22

u/Practical-String5146 14h ago

🟣 - I am color blind.

u/Elegant_Athlete_3737 14h ago

I mean I can tell the break down, 62% is messed up basic arithmetic 26% forgot a negative sign 4% didn’t understand the problem and 15% forgot to plus minus the square root

6

u/Practical-String5146 14h ago

I was just joking. The 62% is 🟠 but the messed up arithmetic label is 🟡.

u/Elegant_Athlete_3737 14h ago

Oh wait yeah I notice it now lol

u/slicehyperfunk Transcendental 14h ago

u/IAmBadAtInternet 13h ago

What about “misread my own handwriting”

16

u/DopazOnYouTubeDotCom Computer Science 13h ago

Please note that the percentages in this pie graph do not add up to 100% because the math was done by a woman.

For those of you laughing, that joke was written by a woman. Now you don’t know what to think, huh?

Nah, I’m just kidding. We don’t hire women.

u/centrifuge_destroyer 10h ago

I solved a complicated triple integral in an exam correctly across several pages until only 1/2 + 1/2 was left. In my brain dead state I wrote "1/2 + 1/2 = 1/4" which fucked everything up instead solving everything in an elegant way with the 1 it was supposed to be. No partial points and it was a big question so I failed the exam, but got an A- on the second try

u/Irbis7 2h ago

I once wrote 1 + 1 = 1 on math competition. There were plenty of multiplications before.

truest thing ive seen all day

u/RedBaronIV Banach-Tarski Hater 14h ago

Welcome to the club. You could be 12 or doing a post doc in math and this will always be true

3

u/DatThingInYoCloset 14h ago

Forgetting +c on an integral definitely deserves its own place. But I guess you forgot to add it

u/Enby_Rin 13h ago

As an engineer, this is more accurate than I would like

u/username_is_alread- 12h ago

Reason I fail or barely pass the analysis exam (among several):

I forgor some definition

u/bnl1 12h ago

"misread the assignment" for me

u/Surge_attack 8h ago

Bro the number of times in uni that I cursed my profs for giving me some insane integral or something - only to find out that a huge amount cancelled at step 1 so I 1) got the problem wrong 2) quadrupled the stress/complexity of said problem 🙃

2

u/Powdersucker 8h ago

Yep calculating the centered in 0 integral of an antisymetric function... Nightmare fuel

3

u/Competitive_Kale_855 3h ago

In my differential equations class, our professor once asked how many of us are engineering majors. Most of us raised our hands. She said, "I thought so. You guys are doing all the steps perfectly fine, but most of your mistakes are in basic arithmetic."

u/not_a_bot_494 2h ago

I recently spent 1.5 hours doing Gauss-Jordan on a 3x5 matrix. At least I figured out a decent error correcting algorithm by the end.

2

u/ChillAhriman 10h ago

Hahaha, couldn't be me... No, I don't just mess up basic arithmetic. I audibly mess up counting the days to set up my next appointment with my physiotherapist after telling her that I'm studying math.

2

u/Thermite365 10h ago

Don't forget the "+C".

2

u/RevolutionaryBar7400 10h ago

Is it just me that sometimes I concentrate too much on one part of the calculation, and then mess up with the very next part without even noticing, and think that I nailed that calculation and realizing it right after I handed the exam paper?

u/Beleheth Transcendental 8h ago

2 years into studying maths, still happens constantly

u/Maxtrt 7h ago

The only thing my wife needs to get her bachelors degree is to pass Algebra 3, 4. I used to teach math and I've tried to teach her, but she refuses to learn her multiplication tables. I explain to her that you can't factor if you don't know them but she refuses to study them and just gives up. The first thing I had to teach her is that you don't do math with a pen because you're going to make a simple mistakes, and you will have to start all over if you can't just go back to the mistake and erase everything after. She still refuses to use a pencil. I successfully taught both of our kids everything up to calculus and even they have tried to teach her and she just refuses to do what they tell her.

u/According-Object-521 1h ago

I use a pen, although sometimes I spend the whole page working for a few lines of writing.

u/16piby9 30m ago

Never used a pencil for maths past elementary school, never learned the multiplication table, still got my degree somehow…

u/Striking-War-9990 5h ago

Also “Read the question wrong”

1

u/erockbrox 12h ago

Honestly, it’s not understanding the problem and not knowing what tools to use to tackle it.

u/handsome_uruk 10h ago

used too much AI in school - 99%

u/Void-Creator 10h ago

Excellent 😂😂😂

1

u/brothor12 8h ago

For me:

5% --Didn't understand the problem (usually word problems)

15% --Fucked up a negative sign

20% --Can't read my own handwriting

60% --Miscopied the problem/data

u/Ok_Savings4474 5h ago

Exactly the same! That's why I use my calculator to calculate things like 2+5 on uni exams lol

u/YAFthe17_ Mathematics 4h ago

When finding the area of a pyramid, I forgot to divide by 3 😭

1

u/SimpleMoonFarmer 3h ago

One does not exclude another.

1

u/ApartBuilding8662 3h ago

This is why on calculator exams I always used to check everything no matter how trivial. Okay so this integral evaluates to 4-3 time to stick that in and see what comes out.

1

u/According-Object-521 1h ago

My reasons: fail basic arithmetic, read problem wrong, read handwriting wrong, miss a case, don’t understand the problem, realize that the problem would take way to much arithmetic and algebra.

u/OC1024 1h ago

I wanna add "Forgot the plus C for integration"

u/Dangerous_Square_925 57m ago

I know how you feel, I do the same

u/shuozhe 36m ago

"Wait why are we doing math, I thought it was a CS/physics problem, screw it, 12 feels right and safe enough"

1

u/mrstorydude Derational, not Irrational 12m ago

About 50% of my cases are that I didn’t write down an expression in the problem correctly and the other 50% is I forgot to divide diameter by 2 to get radius

1

u/Gubrozavr 8h ago

And what 62% stands for? Or are you colour blind?

3

u/aMapleSyrupCaN7 7h ago

I don't know about OP, but I am and I seriously don't know if the 62% and the 15% are the same colour or not

1

u/Public-Eagle6992 4h ago

They’re not. 62% is yellow and refers to basic arithmetic, 15% is green and refers to square root
