I have this question and I'm not sure if what I have is correct, I was wondering if someone could explain where the laws are and why and if I am correct or not? Thankyou.
Consider the following calculation. State which laws of arithmetic are used and indicate at what stage they are used.
4 x 37+ (56 + 4 x 13) = 4 x 37 + (4 x 13 + 56) ( I think this line shows Commutative law)
= (4 x 37 + 4 x 13) + 56 ( I think this line shows Associative law)
= 4 (37 + 13) + 56
= 4 x 50 + 56
= 256.
