Corners I am making an investigation into corners of various sized squares and rectangles on a number grid. In the end of my investigation I hope to create a formula that will help me solve the difference of the corners or rectangle on a any size number grid.

Please find a diagram of what to do and how to do it below. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 (1) Multiply the blue numbers and then the yellow numbers (2) Subtract the sum of the two yellow numbers from the sum of blue (55x46 (=2530)) - (45x56 (=2520)) = 10 As you can see the answer came out as 10. I tried the same sized square on the number grid again and choose the section, 58 59 68 69 68 multiplied by 59 equals...
