Respuesta :

In mathematics, the associative and commutative qualities were laws that are constantly used to add & multiply.

What is associative property?

The associative property indicates that can group number again the same response is obtained as well as the flipping property shows that you might switch numbers around and always reach the very same solution.

Associative rules say that this does not matter to arrange the integers. The legislation contains for adding & multiplying, and does not include subtraction and division.

          a + (b + c ) = (a + b ) + c  ⇒   Associative property of addition

          a + b = b + a  ⇒  commutative property of addition.

       

As we show above both the property used for the addition and no used for the subtraction, that is why before applying the property Juan applied reverse additives.
