Question

Explain how to write an equivalent expression using fhe associative property. 2+ (11 + y)

Answer 1

The associative property of addition is a property which allows terms in an addition expression to be "switched around." For example, the addition property says that the following two expressions are equal:

`5 + (4 + 3)`

`(5 + 4) + 3`

Applying this to this problem, we can move the parentheses to cover the 2 + 11 to make a new expression, as shown below:

`2 + (11 + y) = (2 + 11) + y`

A new expression could be (2 + 11) + y.
