Question

(a-b) -c = a-(b-c) ;
a=10, b=20, c=2 in associative property methods
​

Answer 1

(10-20)-2 = 10-(20-2)

(-10)-2 = 10-(18)

-12 is not equal to-8

hope this is helpful

Answer 2

(10 - 20) - 2 = 10 - ( 20 - 2)

-10 × -2 = 10 (- 20 +2)

20 = 10 ( -18)

20 is not equal to -180

hence it is not an associative property.

■ Associative property will not go for subtraction and division.
