Properties of addition
Key Notes :
🎯 Associative property:(k + m) + n = k + (m + n)
You can group the addends with brackets and get the same sum.
Learn with an example
✈️ Which equation shows the associative property of addition?
- 4 = 4 + 0
- 7 = 1 + 4 + 2
- 0 + 4 = 4
- (7 + 4) + 6 = 7 + (4 + 6)
- (7 + 4) + 6 = 7 + (4 + 6)
- This equation shows the associative property. The grouping of the addends is changed.
✈️ Which property of addition is shown?
4 + (5 + 1) = (4 + 5) + 1
- associative
- commutative
- identity
- 4 + (5 + 1) = (4 + 5) + 1
- This equation shows the associative property. The grouping of the addends is changed.
✈️ Which equation shows the associative property of addition?
- b + (c + d) = (b + c) + d
- b = b + 0
- c + d = b + c
- b + c = c + b
- b + (c + d) = (b + c) + d
- This equation shows the associative property. The grouping of the addends is changed.
