Question

Verify a – (– b) = a + b for the following values of a and b : a = 118, b = 125

Answer 1

Question: Verify a – (– b) = a + b for the following values of a and b : a = 118, b = 125

Solution: To verify the above expression put the values of a and B in the expression,solve it then verify the expression.

LHS:

$a - ( - b) \\ \\ = 118 - ( - 125) \\ \\ = 118 + 125 \\ \\ = 243$
RHS :
$a + b \\ \\ = 118 + 125 \\ \\ = 243$
thus LHS = RHS.

Answer 2

Given :

a - (- b) = a + b

we know, that ( - ) x ( - ) = ( + )

Given :

a = 118 and b = 125

substituting the values of "a" and "b "

a - (- b) = a + b

118 - (- 125) = 118 + 125

118 + 125 = 118 + 125

243 = 243



Hence : Values are same.

Verified : a - (- b) = a + b
