Question

Verify: a − (−b) = a + b, for the following values of a and b

i) a = 25, b = 12

ii) a = 113, b = 16​

Answer 1

Answer:

Step-by-step explanation:

i) a=21b=18

We have a−(−b)

⇒a=21−(−18)=39

and a+b=21+18=39

(ii) a=118b=125

We have a−(−b)

⇒18−(−125)=243

and a+b=118+125=243

Hence proved a−(−b)=a+b

Answer 2

Step-by-step explanation:

25-(-12)=25+12

25+12=37

37=37

it's the equal

113-(-16)=113+16

113+16=129

129=129

it's the equal
