Which property is illustrated below?

Question

3 + [7 + (5)] = 3 + [(5) + 7]

a) Identity property of addition

b) Commutative property of addition

c) Associative property of addition

Answer 1

Commutative Property.

Like a worker who communtes the numbers have "traveled".

Answer 2

It is Associative property of addition because the associative property is a property of some binary operations, which means that rearranging the parentheses in an expression but not change the result. For example, (2+3)+4=2+(3+4), and their answer is 9. While the commulative property is the swaping numbers not parentheses.
