There are nine squares in a 3 x 3 square grid. Four of them will be painted white, how many will be painted black?
I need good explanation, not just the answer, will we use division? Mult?
There are 9 squares, and 4 of them will be painted white, so that means that the remaining squares will be painted black. 9-4=5, so 5 squares will be painted black.
