2) 6 + 3 = 5 + 4
3) 5 + 1 = 1 + 5
4) 1 + (7 + 4) = (1 + 7) + 4

Answer: 4

SOLUTION 1 :

Associative property: (d + f) + g = d + (f + g)
You can group the addends with brackets and get the same sum.

1 + (7 + 4) = (1 + 7) + 4

This equation shows the associative property. The grouping of the addends is changed.

Which property of addition is shown

a + (b + c) = (a + b) + c

1) identity
2) associative
3) commutative
4) zero

Answer: 2

SOLUTION 1 :

Associative property:
You can group the addends with brackets and get the same sum.

a + (b + c) = (a + b) + c

This equation shows the associative property. The grouping of the addends is changed.

Which equation shows the distributive property of multiplication

1) 4x(8x9) = (4x8)x9
2) (4-3)x0 = 4x0-3x0
3) 0 = 0x5
4) 3x9 = 9x3

Answer: 2

SOLUTION 1 :

Distributive property:
You can multiply a sum by multiplying each addend separately.

The distributive property works with subtraction, too

(4 – 3)x0 = 4x0 – 3x0

This equation shows the distributive property. Multiplication distributes over addition or subtraction.

Which equation shows the identity property of multiplication

1) (3x1)x8 = 3x(1x8)
2) 0 = 6x0
3) 8x(7+3) = 8x7 + 8x3
4) 8 = 1x8

Answer: 4

SOLUTION 1 :

Identity property:
Multiplying by 1 does not change a number

8 = 1x 8

This equation shows the identity property. Multiplying by 1 does not change the number.

Which equation shows the identity property of addition

1) 0 + 9 = 9
2) 7 + 8 = 15
3) 6 + (2 + 1) = (6 + 2) + 1
4) 2 + 7 = 5 + 4

Answer: 1

SOLUTION 1 :

Identity property: q = 0 + q
Adding zero does not change a number.

0 + 9 = 9

This equation shows the identity property. Adding zero does not change the sum.

Which equation shows the zero property of multiplication

1) 7 = 7x1
2) 0x7 = 0
3) 2x(9x8) = (2x9)x8
4) 3x(5+0) = 3x5+3x0

Answer: 2

SOLUTION 1 :

2) 0 + m = m
3) n + p + q = m
4) (m + n) + p = m + (n + p)

Answer: 1

SOLUTION 1 :

Commutative property:
You can add numbers in any order and get the same sum.

m + n = n + m

This equation shows the commutative property. The order of the addends is changed.
