Today I learned how to make long problems easier. We focused on reviewing what I learned about addition then learned about multiplication. I’ve already done both, but this is practice to start the pre-algebra stuff. I learned the commutative property, the associative property, and the order of operations. My mom found a grammar error in the textbook. Derp!

In the **commutative property**, the numbers are moved around (“commuted”) on the two sides of the equation.

In the **associative property**, the numbers stay in the same place but are grouped (“associated”) differently.

1. **Addition is commutative!**

Let a and b be numbers. Then

A + b = b + a.

2. **Addition is associative!**

Let a, b, and c be numbers. Then

(A + b) + c = a + (b + c).

3. **Adding zero!**

let a be a number. Then

a + 0 = a

4. **Multiplication…**
