Question

I have to write if it is associative property, closure property, commutative property, additive inverse and so on in the following exercise. (x + 2y) + 3z = x + (2y + 3z)

Answer 1

Step-by-step explanation

To get which property we are working with, we need to compare the two sides to check what changes.

We can see that the order and the terms don't change, we only change the position of the parenthesis.

All the operations we have are additions, and changing the parenthesis is the same as changing the groups of the addends. In addition, changing the groups don't affect the result, and this is called associative property of addition.

Answer

Associative property
