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.

This happened so often when I was a server. I lost out on numerous tips because self-righteous, mathetmatically-challenged people got furious when I actually paid for a small portion of their meal out of my own pocket to make it easier. Most of the time, they'd throw a fit and leave. Sometimes they'd confront me, or ask for my manager, but usually explaining to these MENSA candidates didn't work and they'd stomp out. So, I started walking around for 8+ hours a night with an extra pound of effing change in my pockets to make the knuckleheads happy.

I was a server for 5 years. I would get change from the bar at all 10 of the restaurants where I worked. They certainly didn't expect servers to carry around jingle change all day.

Obviously, and then she got this theatre, and presumably they were so annoyed they didn't tip. So yes, the restaurant lost out quite solidly by giving 20cents unasked.

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.
