Hey all, I need some guidance on a problem I've been working on involving a grid formula. Please see the problem below:
(i) Consider a n x n grid of uniform size. Guess a formula for the number of different squares (of varying size) and prove it.
Above is an illustration for a 2 x 2 grid.
(ii) What is your answer when we consider the same problem for a m x n grid?
Not sure where to start off with this one....all help is appreciated!
