Name the property of real numbers illustrated below. Be specific with the naming (include “of addition” or “of multiplication,” if applicable).


(-9)(8) = (8)(-9)





I never did this before so Im guessing


(-9) would be a higher value=-negative 9? base on the real number line- I have no clue ?

This is called the "Commutative property of multiplication".


You can remember this because


1)it is multiplication


2) when you commute, you go from home to work and then work to home. When you look at the problem it looks like home to work=work to home.





All this property is saying is that you can change the order of the numbers when you multiply and it doesn't change the outcome. -9 time 8 is the same thing as 8 times -9.





The same is true when we commute to work. The distance is the same even though we have chaned the direction in which we are traveling.





I hope that helps you remember. If you would like clues to help you remember the other properties, just ask.

It means you can rearrange the terms and the answer will remain the same.


Example:


A x B = B x A
