Back

The identity property of addition states that when you add zero to any number, the result is that number. For example, 5 + 0 = 5.

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, (2 + 3) + 4 = 2 + (3 + 4).

Front

What is the commutative property of addition?

Back

The commutative property of addition states that changing the order of the numbers you are adding does not change the sum. For example, 4 + 5 = 5 + 4.

Front

What is 0 + 10?

Back

0 + 10 = 10 (Identity property of addition).

Front

What is 8 + 0?

Back

8 + 0 = 8 (Identity property of addition).

Front

What is 4 + 7?

Back

4 + 7 = 11 and 7 + 4 = 11 (Commutative property of addition).

Front

What is (9 + 4) + 5?

Back

(9 + 4) + 5 = 18 and 9 + (4 + 5) = 18 (Associative property of addition).

Front

If you have 3 + 2 + 1, how can you group them?

Back

You can group them as (3 + 2) + 1 or 3 + (2 + 1), and both will equal 6 (Associative property of addition).

Front

What happens if you add two numbers in a different order?

Back

The sum remains the same. For example, 6 + 2 = 8 and 2 + 6 = 8 (Commutative property of addition).

Front
