Introduction: I'm going to investigate the difference between products on a number grid first I'm going to draw a box round four numbers then I will find the product of top left, bottom right numbers, and then I'm going to do the same with the top right, bottom right numbers in the box. I'll will then calculate the difference between these products. Not only I am going to investigate squares, but also rectangles, I'll use algebra to try and find a formula or a general rule that will give me this difference for any size shape. I'm going to draw a box round four numbers then I will find the product of top left, bottom right numbers, and then I'm going to do the same with the top right, bottom right numbers. 12 13 22 23 The difference between 286 and 276 is 10 because 286 - 276 = 10 13 x 22 = 286...
