Been a little stuck on this question,
any help would be greatly appreciated!!
Consider the following calculation. State which laws of arithmetic are used and indicate at what stage they are used.
4 × 37 + (56 + 4 × 13) = 4 × 37 + (4 × 13 + 56)
= (4 × 37 + 4 × 13) + 56
= 4(37 + 13) + 56
= 4 × 50 + 56
= 256
