Properties of Real Numbers

What is the commutative property of addition?

• The commutative property of addition states that the sum of any number and one is the number itself.

• The commutative property of addition states that changing the order of the addends does not change the sum.

• The commutative property of addition states that changing the order of the addends changes the sum.

• The commutative property of addition states that the sum of any number and zero is the number itself.

Use the distributive property to simplify the expression: 2 * (4 + 6).

• 2 * (4 + 6) = 2 * 4 + 2 * 6 = 4 + 6 = 10

• 2 * (4 + 6) = 2 * 4 + 2 * 6 = 8 + 12 = 20

• 2 * (4 + 6) = 2 * 4 + 2 * 6 = 6 + 10 = 16

• 2 * (4 + 6) = 2 * 4 + 2 * 6 = 8 * 12 = 96
