Question 8(i) Verify a - (-b) = a + b for the following values of a and b. a = 21, b = 18
Given,a = 21, b = 18 a - (-b) = 21- (-18) = 21 + 18 = 39 a + b = 21 + 18 = 39 ∴ a - (-b) = a + b = 39
Verify a−(−b)=a+b for the following values of a and b.(i) a=21, b=18 (ii) a=75,b=10
Verify a − (−b) = a + b for the following values of a and b.
(i) a = 21, b = 18
(ii) a = 118, b = 125
(iii) a = 75, b = 84
(iv) a = 28, b = 11
Question 8(ii) Verify a−(−b) = a + b for the following values of a and b. a = 118, b =125
Question 8(iv) Verify a - (-b) = a + b for the following values of a and b. a = 28, b = 11
