Solve 3x3 matrices here! Highly unoptimized! Only type numbers into the boxes except for operation! Instead put +, -, or x
Only works with addition, subtraction, multiplication, and one scalar multiplication case! Smaller addition/subtraction matrices like 1x1, 1x2, 1x3, 2x1, 2x2, 2x3, 3x1, and 3x2 grids can be solved with this, just fill extra variables here with zeroes and disregard them.
