A fun little bit of arithmetic that has been making the rounds on the Internet, it involves six steps to blow your mind, as long as you're not 100 years old.

First you multiply your shoe size by five. Step two is to add 50 to that number, and then you take that total and multiply it by 20. Next up, you add 1,015 to that total and then subtract the year you were born.

Voila, the first two numbers of the four-digit number you get are your shoe size, and the next two numbers are your age.

The only thing that can throw a kink into the fun is if you've already had a birthday this year, or if you're 100 years old, according to Real Clear Science. Give it a shot, and see how you do!
