Question

write a pair of integers whose sum gives a) a negative integer ,b) zero, c) an integer smaller than both the integers ,d) an integer smaller than only one of the integers, e) an integer greater than both the integers

Answer 1

Hi ,

Let a , b € Z


A ) a = - 6 , b = 4

a + b = -6 + 4 = -2 ( negative integer )

B ) If a = - 3 , b = 3 ,

a + b = -3 + 3 = 0

C ) if a = -2 , b = -3

a + b = -2 + ( -3 )

= -2 - 3

= -5 ( less than both the

integers )

D ) if a = -4 , b = 5

a + b = -4 + 5 = 1 < b

E ) if a = 8 , b = 6

a + b = 8 + 6 = 14

I hope this helps you.

Answer 2

Hi,

Here is your answer,

1) a = - 6 , b = 12
 = - 6 + 12   { Add both the numbers } A + B
 
= 6
 2) a = - 4 , b = 4
 = - 4 + 4  { Add both the numbers ) A + B

= 0
3) a = - 5 , b = - 6 
 = -5 + (-3)
= -5 - 3 
= -8 
4)  a = - 4 , b = 5

 = -4 + 5 = 1 { Add both the numbers A + B }
  5)a = 5 , b = 7
 = 5 + 7 = 12 { Add both the numbers } 


Hope it helps you !
