Number Grid Investigation

I’m going to investigate about ten different squares randomly across the grid. And put them into a table, which I will have my working out underneath. I will do this to discover a pattern with my answer and see how the pattern varies between the different shape and rectangles. I will also use about six to eight rectangles in my grid investigation.
