Can you use the distributive property to help you expand and factor expressions?
Yes.
Why do we have to do the Distributive property rather than using order of operations?
None whatsoever. You might find the distributive property useful when trying to calculate 39*74. Of course, if you are familiar with the 39 times table or the 74 times table, the distributive property is a complete waste of time! But somehow I doubt that level of arithmetic competence.
Why do you use the addition property of equality?
Why? - Mainly to help in solving equations.
How can associative property of multiplication can help solve math problems mentally?
You can do the easy bits first. Thus, to calculate 7*5*2, instead of doing 35*2 = 70, you can calculate 7*10 = 70. By itself, the associative property is not as useful as it is in combination with the commutative and distributive properties.
What does the math term distributive?
If you're talkin about the distributive property, here's an example of how to use it: 5(x + 4) You do 5*x= 5x and 5*4= 20 and you get 5x + 20 Get it? Hope could help :)
