# Worksheet on Addition and Subtraction using Number Line

Practice the questions given in the worksheet on addition and subtraction using number line. We know, adding a negative number means moving to the left-side on the number line and adding a positive number means  moving to the right-side on the number line.

With the help of the below number line add or subtract the following numbers.

1. Use a number line to evaluate each of the following:

(i) (+7) + (+5)

(ii) 0 + (+9)

(iii) (+6) + (+3)

(iv) (+1) + 0

(v) (+5) + (+8)

(vi) (+5) + (+3)

(vii) (+8) + 0

(viii) (+3) + (+8)

2. Evaluate the following using a number line:

(i) (-3) + (+7)

(ii) (-2) + (+6)

(iii) (-4) + (+8)

(iv) 0 + (+1)

(v) (-1) + (+5)

(vi) (-5) + (+3)

(vii) (-8) + (+1)

(viii) (-4) + (+9)

3. Add the following using number line:

(i) (+7) + (-3)

(ii) (+9) + (-1)

(iii) (+4) + (-7)

(iv) (+9) + (-9)

(v) 0 + (-2)

(vi) (+5) + (-3)

(vii) (+3) + (-2)

(viii) (6) + (-9)

4. Find the sum of the following using number line:

(i) (-4) + (-8)

(ii) (-2) + (-7)

(iii) (-1) + (-5)

(iv) (-7) + (-7)

(v) (-8) + (-1)

(vi) (-9) + (-2)

(vii) (-5) + (-4)

(viii) (-6) + (-3)

5. Subtract the following using number line:

(i) (+10) - (+3)

(ii) (+9) - (+1)

(iii) (+6) - (-2)

(iv) (+4) – (-2)

(v) (+7) - (-1)

(vi) (-8) – (+5)

(vii) (-9) - (+4)

(viii) (-8) – (+3)

(ix) (+2) - (-1)

(x) (-10) - (-10)
