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?!

I know how the guy/girl thought it was 9,125 dollars with the quarter. Because he probably did 25x365 and not 0.25x365

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.

And even the testing math is not true, as positive rates do not simply scale with the number of tests but are dependent on many factors.

But Disney fired all staff and has almost no expenses. So they will deduct their "losses" in the next taxdeclaration and they still end up making profit.

Walmart always has weird prices like that on their app! I needed cinnamon and the options were to buy one for $4.50 or two for $2.99. I didn’t even look at the unit price, it was probably way off too. I do not need this much cinnamon.
