(b) – 30 and – 20 \nDifference = – 30 – (- 20) \n= -30 + 20 = – 10<\/p>\n
(c) – 12 and + 12 \nDifference = – 12 + (12) \n= -12 + 12 = 0<\/p>\n

Question 2. \n(a) Write a pair of negative integers whose difference gives 8. \n(b) Write a negative integer and a positive integer whose sum is – 5. \n(c) Write a negative integer and a positive integer whose difference is – 3. \nAnswer: \n(a) – 13 and – 21 \nDifference = -13 – (- 21) \n= – 13 + 21 = 8<\/p>\n
(b) – 15 and 10 \nsum = – 15 + 10 = – 5 \n(c) – 1 and 2 \nDifference = – 1 – (+ 2) \n= – 1 – 2 = – 3<\/p>\n
Question 3. \nIn a quiz, team A scored – 40, 10, 0 and team B scored 10, 0, – 40 in three successive rounds. Which team scored more? Can we say that we can add integers in any order? \nAnswer: \nTotal score of team A = (- 40) + 10 + 0 \n= – 40 + 10 + 0 = – 30 \nTotal score of team B=10 + 0 + (- 40) \n= 10 + 0 – 40 = 10 – 40 = – 30 \nSo, both the team scored equal. Yes, we can say that we can add integers in any order.<\/p>\n

Question 4. \nFill in the blanks to make the following statements true: \n(i) (- 5) + (- 8) = (- 8) + (………………) \n(ii) – 53 + …………… = – 53 \n(iii) 17 + ……………… = 0 \n(iv) [13 + (- 12)] + (…………..) = 13 + [(- 12) + (- 7)] \n(v) (- 4) + [15 + (- 3)] = [- 4 + 15] + ……………. \nAnswer: \n(i) (- 5) + (- 8) = (- 8) + (- 5) \n(ii) – 53 + 0 = – 53 \n(iii) 17 + (- 17) = 0 \n(iv) [13 + (- 12)] + (- 7) = 13 + [(-12) + (- 7)] \n(v) (-4)+ [15 +(-3)] = [-4 + 15] + (- 3)<\/p>\n","protected":false},"excerpt":{"rendered":"
