Q4 of 15 Page 26

Write a pair of integers whose sum gives

a) a negative integer


b) an integer smaller than both the integer


c) an integer smaller than only one of the integer


d) an integer greater than both the integer

Given: - To choose any two integers


a)To get the sum of two integers negative


We have to choose a smaller number with + sign and larger number with – sign


Therefore Let numbers are (+ 5) and (– 8)


Addition of the above numbers


(+ 5) + (– 8) = (– 3)


b) To get an integer smaller than both the integers


we have to choose (– sign) numbers as they are smaller as they


move left from 0 on number line.


Therefore, Let numbers be (– 6) and (– 4)


Addition


(– 6) + (– 4)


= – 6 – 4


= – 10


c) To get a number smaller than any one number


we have to choose two different sign numbers


Therefore, Let numbers be (– 7) and (+ 5)


Addition


(– 7) + (+ 5)


= – 2 hence, smaller than (+ 5) and greater than (– 7)


d) To get integer greater than both numbers


we have to choose + sign numbers


Therefore, Let numbers are (+ 2) and (+ 3)


Addition


= (+ 2) + (+ 3)


= + 5
