Question

The equation, a + (b + 7) = (b + 7) + a, is an example of which property?

A. distributive property
B. associative property of addition
C. commutative property of addition
D. associative property of multiplication

Answer 1

B. Commutative Property

Explanation:

A. Distributive property :

for example we take 256 × 1008

256 × 1008

256 ×(1000 +8)

(256 × 1000) + (256 × 8)

256000 + 2064

Answer : 258064

Distributive is distributing a number that contains 0's to make it easier for one self

B. Associative Property of Addition :

for example (230 + 125) + (390 + 460)

if we change it like this or in any order than particularly changes the grouping

(230 + 460) + (390 + 125)

D. Associative Property of Multiplication

(230 × 125) × (390 × 460)

it's the same as the previous example just in Multiplication
