Algebra Coursework Introduction This piece of coursework is called 'Opposite Corners' and is about taking squares of numbers from different sized number grids. I will be multiplying the opposite corners together and subtracting to find the difference. I will make a prediction for each grid and use a few examples to find a formula to prove my prediction right. Method To calculate the difference of the squares drawn on the number grids, I will be multiplying each of the diagonal numbers. Then I will subtract the smaller number away from the larger number to find the difference of the square. To do this I will use algebraic equations, I will use 'N' to represent the smallest number and 'g' to represent the grid size. I will then compare my results to 'N', then to complete the equation by expanding, simplifying and cancelling the brackets to get my final result. Prediction I predict that a 2x2...
