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 sum is that number. For example, 0 + 98 = 98.

What is the Associative Property of Addition?

Back

The Associative Property of Addition states that the way in which numbers are grouped when adding does not change the sum. For example, (a + b) + c = a + (b + c).

Fill in the blank: (10 + __) + 17 = (17 + 9) + 10. What is the missing addend?

Back

9

Front

Provide an example of the Associative Property of Addition using numbers.

Back

An example is (14 + 27) + 7 = 14 + (27 + 7), which shows that grouping does not affect the sum.

What does it mean to 'fill in the blank' in an addition equation?

Back

It means to identify the missing number that makes the equation true.

Front

How does the Identity Property of Addition apply to the number 0?

Back

The Identity Property shows that adding 0 to any number does not change the value of that number.

Front

What is the result of using the Associative Property of Addition on the numbers 5, 10, and 15?

Back

(5 + 10) + 15 = 5 + (10 + 15) = 30.

Front

What is the significance of the order of numbers in addition?

Back

In addition, the order of numbers does not affect the sum due to the Commutative Property, which states a + b = b + a.

Front

What is the Commutative Property of Addition?

Back

The Commutative Property of Addition states that changing the order of the addends does not change the sum. For example, 3 + 4 = 4 + 3.
