Mathematical Properties of Addition and Multiplication

Front

What does -4 + 4 = 0 represent?

Back

Additive inverse: The sum of a number and its opposite is zero.

Front

What does (2 + 7) + 5 = 2 + (7 + 5) represent?

Back

Associative property of addition: The way numbers are grouped does not change their sum.

Front

Which property does 9 x 1 = 9 represent?

Back

Identity property of multiplication: Any number multiplied by 1 remains unchanged.

Front

What does a + 0 represent?

Back

Identity property of addition: Any number plus zero remains unchanged.

Front

Are (5 x 10) x 2 and 5 x (10 x 2) equivalent?

Back

Yes, Associative Property: The way numbers are grouped does not change their product.

Front

What is the Commutative Property of Addition?

Back

The order of numbers can be changed without affecting the sum (e.g., a + b = b + a).

Front

What is the Commutative Property of Multiplication?

Back

The order of numbers can be changed without affecting the product (e.g., a x b = b x a).

Front

What is the Associative Property of Multiplication?

Back

The way numbers are grouped does not change their product (e.g., (a x b) x c = a x (b x c)).

Front

What is the Identity Property of Addition?

Back

Any number plus zero equals the number itself (e.g., a + 0 = a).

Front

What is the Identity Property of Multiplication?

Back

Any number multiplied by one equals the number itself (e.g., a x 1 = a).
