Draw hops on a number line to show the addition statement and find the sum :
`{:(a.,3 + (-7),b.,(-4) + 6),(c.,3 + 5,d.,(-2) + (-5)):}`

Draw hops on a number line to show the subtraction statement and find the difference : {:(a.,5-(-2),b.,(-2)-4),(c.,3-8,d.,(-4)-(-7)):}

Draw hops on a number line to show the addition statement and find the sum : i. 5 + 8 ii. 2 + (-4) iii. -2 + (-5) iv. -3 - (-4)

Draw hops on a number line to show the subtraction statement and find the difference : i. 6 - 5 ii. 4 - 7 iii. 4 - (-2) iv. -3 - (-4)

Add, each pair of rational numbers, given below, and show that their addition (sum) is also a rational number : (v) (5)/(-6) "and" (2)/(3)

Add each pair of rational numbers, given below, and show that their addition (sum) is also a rational number : (i) (7)/(15) "and" (3)/(5) (ii) (2)/(7) "and" 2 (iii) (3)/(8) "and" (-5)/(12) (iv) (7)/(-15) "and" (2)/(-3) (v) (5)/(-13) "and" (11)/(26)

Draw number lines and locate the points on them : (a) 1/2,1/4, 3/4, 4/4, (b) 1/8, 2/8, 3/8, 7/8, (c) 2/5, 3/5, 8/5, 4/4

Use number line and add the following integers : (a) 9+(-6) (b) 5+(-11) (c) (- 1 )+ (-7) (d) (-5) + 10 (e) ( -1 ) + ( -2 ) + (- 3 ) (f) ( - 2 ) + 8 + (- 4)

The mean deviation of the numbers 3, 4, 5, 6, 7 from the mean is (a) 25 (b) 5 (c) 1.2 (d) 0

Verify the result by performing the addition on a number line: a. (-5) times 3" b. "6 times (-2)
