Associative Properties of Addition and Multiplication
If ...then...
If a, b, and c are real numbers then
a + (b + c) = (a + b) + c = a + b + c
a x (b x c) = (a x b) x c = a x b x c
-
What properties are these
If a, b, and c are real numbers then
a + (b + c) = (a + b) + c = a + b + c
a x (b x c) = (a x b) x c = a x b x c

Additive Inverse Property
For any real number a, finish line
For any real number a, a + (-a) = -a + a = 0
-
what property is this
For any real number a, a + (-a) = -a + a = 0
additive inverse property
-
What four properties of addition are there?
What are their formulas?
- 1. Identity Property of addition
- -For any real number a, 0 + a = a + 0 = a
- 2. Commutative property of addition
- -If a and b are real numbers, then a + b = b + a
- 3. Additive Inverse Property
- -For any real number a, a + (-a) = -a + a = 0
- 4. Associative Property of Addition
- If a, b, and c are real numbers, then a+(b+c)=(a+b)+c.
-
Match the properties with the numbers
1. For any real number a, 0 + a = a + 0 = a
2.If a and b are real numbers, then a + b = b + a
3. For any real number a, a + (-a) = -a + a = 03. 4. If a, b, and c are real numbers, then a+(b+c)=(a+b)+c.
- 1. Identity Property of addition
