Question 93635
Hello!

First, I will answer you questions then I will explain the basic properties of addition and multiplication.

1. What is the property of a*(b*c)=(b*c)*a---this is CPM---
2. What is the property of b(c+a)=b*c+b*a---this is DPMA---
3. What is the property of a*b+0=a*b---this is IPM---

Now I will explain.

Oh I have an idea, I will just post a lesson about the properties.
You just need to look at it.

Thank You!
