We might act like Muppets sometimes, but we’re nowhere near as good at counting as Count von Count. One! Two! Three! Hahaha. And that’s more or less where our worldly wisdom with numbers ends.

(Un)fortunately, we’re not the only ones whose brains sometimes derp out and throw their math skills out of whack! And that’s what the ‘They didn’t do the math’ subreddit is all about. It documents all of the biggest math fails on the net and all of the times people messed up when doing school-level counting. (Just remember not to mix this community up with its counterpart, the ‘They did the math’ subreddit.)

Check out some of the funniest ‘They didn’t do the math posts’ and upvote your fave pics by giving them a big old upvote. Do you have any embarrassing math fails to share with all the other Pandas? Drop us a comment below. Who said that math can’t be fun?!

The subreddit has over 24.3k members and has been active for 6 and a half years at the time of writing. And the community is all about making your inner numbers’ wiz groan and cringe. There’s nothing like feeling like a genius at math when you compare yourself to the worst of the worst, is there?

But suppose that being better than the worst isn’t enough for you. You like a challenge. You enjoy improving yourself. Pushing past your limits. You’re a Panda, after all! Luckily, there are countless (pun not intended) free and paid resources online to help you sharpen your skills with numbers. From big names like Khan Academy to small scale websites and projects that you’ll find hiding in the cracks of the internet, right in-between posts about cats.

While some peeps have an easier time learning math, I sincerely believe that everyone can reach the genius tier if they put in enough time, effort, and focus. I for one was really awesome at math when I started school (multiplying stuff was my bread and butter). However, I started struggling when they started throwing in letters and weird concepts into my calculations. I’m sure that more than one of you has been there, dear Readers.

But one thing that I learned was how much carving out an hour or two for practicing basic math problems helped me out. That and knowing some amazing math wizards who explain to you the illogical logic behind numbers. TL;DR—practice makes perfect and soon enough you’ll be a Muppet like Count von Count.

It depending what mode you put your calculator on. Usually they on the standard mode which count each time you put a mark, when scientific mode will count the whole sequence when you hit the equal sign. This is clearly a programmer fault when not showing which order they are using.

Is this an order of operations question? The people who wanna say 10 are reading it like this: (10+10) / 2 = 10. The people who wanna say 15 are reading it like this: 10 + (10 / 2) = 15. The calculator is non-specific on this issue...

It's correct because the division has a higher order of expression than the addition but most people would write 10÷2+10.

Caroline Overill

I just did it on my calculator and it comes out 10 which it should do unless there are brackets around the 10/2. 10/2 plus 10 comes out 15. The calculator just does the operations in the order you tell it.

I had never heard about this. (Not American) The BODMAS rule states we should calculate the Brackets first (2 + 4 = 6), then the Orders (52 = 25), then any Division or Multiplication (3 x 6 (the answer to the brackets) = 18), and finally any Addition or Subtraction (18 + 25 = 43).

To be honest: (in Holland around 1992 the rules changed) Before 1992 you would first do multiply and divide --> then the plusses/minuses. But values within brackets () would go first! So... I think in 1991 in Holland this would have been the correct answer. (For the Dutch: Meneer van Dalen wacht op antwoord --> is dus... dood.)

Well, there is more to this than meets the eye. "If your calculator is NOT a scientific calculator it does NOT follow order of operations and calculates the result in the order in which the entries were made." So, indeed, if this person had been using a simple calculator doing the sum of 10 + 10 = 20, then dividing it by 2 = 10, they'd get that reaction.
