describe how you know that (8+9) + 3 is equivalent to 8+ ( 9 + 3). what is the benefit to using this property? ​

Respuesta :

The equations are equivalent because of PEMDAS. The benefit of using this property is that it is the same procedure each time and you are only adding throughout this equation, so no matter the order you put the numbers in, the outcome will always be the same.
