We found there are 204 squares on a chessboard where the length ofone side is 8 squares (8 x 8).
Imagine a new chessboard has been invented that has a length of 25 squares (25 x 25).
How many squares are there in this new chessboard?!
Length of one side (x)

Imagine your data is like a function machine.
Where... x = length of one siden = total number of squares
You know the input (x) and the output (n), but what is happening in the function machine?
