Answer 2

Given :- Write the properties used in the following :-

(a) 175 + 23 = 23 + 175

(b) (189 - 56) -76 ≠ 189 - (56 - 76)

Answer :-

(a) 175 + 23 = 23 + 175

we know that,

• The commutative property of addition is : x + y = y + x .

checking,

→ 175 + 23 = 23 + 175

→ 198 = 198

therefore, we can conclude that, The commutative property of addition is used in (a) .

(b) (189 - 56) -76 ≠ 189 - (56 - 76)

we know that,

• The associative property of Subtraction is :- (x - y) - z ≠ x - (y - z) .

checking,

→ (189 - 56) -76 ≠ 189 - (56 - 76)

→ 133 - 76 ≠ 189 - (-20)

→ 57 ≠ 189 + 20

→ 57 ≠ 209

therefore, we can conclude that, The associative property of Subtraction is used in (b) .
