rect, since ~ 9+ 167, which | is NOL a negative integer The correct statement is :, one positive and one negative integers are added, we take their difference, lace the sign of the bigger integer. The bigger integer is decided by ignoring the, of both the integers. Por example:, = 56) + (73) #17 (b) (+113) +82«-31, , 16 + (~ 23) 2-7 (dj) 125% (~ 101) 224~, ict five more examples for verifying this staternent., , . Some other examples of additive inverse are as given below: i : y, An, a im J’, , \, , , , > the additive inverse of any integer a is — a and additive inverse of (— a) is a., 1 ect. Subtraction is opposite of addition and therefore, we add the additive, irse of the integer that is being subtracted, to the other integer. For example:, —~73= 56 + additive inverse of 73 = 56 + (73) =-17, , ~—(-73) = 56 + additive inverse of (-73) =56 + 2S =o, , 79) — 45. = (-79) + (- 45) =—124, , 100) — (-172) =-100 + 172 =72 etc., , ast five such examples to verify this statement. _, , we find that for any two integers a and b,, , a—-b=a+additive inverse of b=a+€b), a—(—b)=a+ a a of (—b)=a+b, , t, since (-10) + 3 =—7 ang L10—3 a 36. ca., (-10)+3#410-3, since, 8+(-7)-C4= 55 Th 14 2 ss, , 8+7-4=15-4=l1, 8 +(-7)-(-4)=8-7+4, , anem for each of the following?
