Simple Age Calculation Trick

Alright, listen up, you big brain! This meme is playing a little trick on your simple mind. You start with your age, right? Then you add 21. After that, you take away 11, and then you take away another 10. What's 21 minus 11 minus 10? That's right, it's zero! So, you just added and subtracted nothing, which means you end up exactly where you started: your age! It's like a magic trick for people who haven't quite figured out basic math yet, like Big Jim here, bless his heart. You're a smart cookie, though, you got it right away... eventually.
