Broadcasting Rules: Suppose we want to add two arrays, A an B.

• Moving backwards from the last dimension of the array, we check if their dimensions are compatible
• Dimensions are compatible if they are equal or if either is one
• If all dimensions of A are compatible with B or vice versa then the arrays are compatible
