Addition Properties

What is the identity property of addition?

Back

The identity property of addition states that when you add zero to any number, the result is that number. For example, 6 + 0 = 6.

What is the commutative property of addition?

Back

The commutative property of addition states that the order in which you add two numbers does not change the sum. For example, 6 + 5 = 5 + 6.

Front

What is the associative property of addition?

Back

The associative property of addition states that when you add three or more numbers, the way in which the numbers are grouped does not change the sum. For example, 8 + (2 + 1) = (8 + 2) + 1.

What is an example of the identity property of addition?

Back

An example is 7 + 0 = 7.

Front

What is an example of the commutative property of addition?

Back

An example is 4 + 3 = 3 + 4.

Front

What is an example of the associative property of addition?

Back

An example is (1 + 2) + 3 = 1 + (2 + 3).

Front

If you add 0 to a number, what happens to that number?

Back

The number remains the same. For example, 8 + 0 = 8.

Front

What does it mean to say addition is commutative?

Back

It means you can switch the numbers around when adding, and the answer will still be the same.

Front

Can you give an example of the associative property with numbers 2, 3, and 4?

Back

Yes, (2 + 3) + 4 = 2 + (3 + 4). Both equal 9.

Front

What is the sum of 5 + 0?

Back

The sum is 5, demonstrating the identity property.
