Funny how the top two numbers are 7 and 3. Put them together and you get 73, which is actually one of the coolest prime numbers in math!

Why is that?

73 is cool because it’s the 21st prime, and its mirror, 37, is the 12th. Plus, 21 (its mirror) is 7 x 3! Oh, and in binary, 73 is a palindrome too. Pretty near, right?
