Question

1. Identify the property used in the given 30 + 50 = 50 + 30
2. What property on operation of integers is used in -100 + 100 = 0?

Answer 1

• 30+50=50+30 is commutativiy .

• (2+x)+(2×6)=2×(x+6)

(2+x)+(2×6)=2×(x+6)Associative property says that,

(2+x)+(2×6)=2×(x+6)Associative property says that, If (a+b)=ac+bc.

(2+x)+(2×6)=2×(x+6)Associative property says that, If (a+b)=ac+bc.And the operation shows same property. It is associative property of multiplication.
