Fun fact

Fun fact: In Pascal's Triangle, if you want to find binomial coefficients with a certain top number, you look at the numbers on the second or second to last diagonal column of the triangle. It actually corresponds to each top number. If you want to do the same with the bottom number, you just count to the number of rows equal to your bottom number.
(idk what they are called so I just say "top" and "bottom" number)
