Answer 2

Answer:

In mathematics, the closure property refers to how an operation acts on two numbers of a set. That is, in order for a set to satisfy the closure property for some operation, it must be the case that if that operation is performed on any two elements in the set, then the result is also in that set.

1 + 2 = 2 + 1

The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis

(2 + 3) + 4 = 2 +(3 +4)
