Properties of multiplication
key notes :
Commutative property:
You can multiply numbers in any order and get the same product.
3 × 9 = 9 × 3
Associative property:
You can group the factors in any way without changing the result.
7 × (8 × 6) = (7 × 8) × 6
Zero property:
Multiplying by 0 always gives 0.
3 × 0 = 0
Identity property:
Multiplying by 1 does not change a number.
2 = 1 × 2
Distributive property:
You can multiply a sum by multiplying each addend separately.
5 × (7 + 2) = (5 × 7) + (5 × 2)
The distributive property works with subtraction, too.
5 × (7 − 2) = (5 × 7) − (5 × 2)
Learn with an example
🎯 Which equation shows the commutative property of multiplication?
- 7 × 8 + 7 × 5 = 7 × (8 + 5)
- 6 × 1 = 1 × 6
- 5 + 5 + 5 + 5 = 5 × 4
- 0 × 3 = 0
- 6 × 1 = 1 × 6
- This equation shows the commutative property. The order of the factors is changed.
🎯 Which equation shows the zero property of multiplication?
- 8 × (1 × 7) = (8 × 1) × 7
- 0 = 0 × 6
- (2 × 6) × 1 = 2 × (6 × 1)
- 5 × 1 = 5
- 0 = 0 × 6
- This equation shows the zero property. 0 times any number is always 0.
🎯 Which property of multiplication is shown?
🎯 9 × 5 = 5 × 9
- associative
- commutative
- distributive
- zero
- 9 × 5 = 5 × 9
- This equation shows the commutative property. The order of the factors is changed.
