Investigate further. In this investigation I will look at the different number grids and different sized rectangles within these grids, I will explain the patterns and give algebraic equations for the results found during this investigation. I will also try to find a formula and prove my findings. To find out the product difference I need to:- Multiply the top left number with the bottom right and multiply the top right with the bottom left and then - the products from each other. I will first try with a 2 x 2 square. 12 13 22 23 a) 12 x 23 = 276 The difference...
