First we move 3 steps to the right from 0

And then , we move 5 steps to the right

    we reach

 

   ∴ 3 + 5 = 8

 

Add (−3) & (−5) on number line

(−3) + (−5)

9 integers between.jpg

First we move 3 steps to the left from 0

And then , we move 5 steps to the left

  we reach −8
 

  ∴   (−3) + (−5) = −8

 

Add (−3) & (5) on number line

(−3) + (5)

10 integers between.jpg

 

First we move 3 steps to the left from 0

And then , we move 5 steps to the right

  we reach 2

 

  ∴   (−3) +  5  = 2

 

Add (3) & (−5) on number line

3 + (–5)

11 integers between.jpg

First we move 3 steps to the right from 0

And then , we move 5 steps to the left

  we reach −2
 

  ∴   (3) + (5) = −2
