Question 1:

Using the number line write the integer which is:

(a) 3 more than 5

(b) 5 more than −5

(c) 6 less than 2

(d) 3 less than −2

Answer:

(a)

Hence, 8

(b)

Hence, 0

(c)

Hence, −4

(d)

Hence, −5

Question 2:

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)

Answer:

(a)

Hence, 3

(b)

Hence, −6

(c)

Hence, −8

(d)

Hence, 5

(e)

Hence, −6

(f)

Hence, 2

Question 3:

Add without using number line:

(a) 11 + (− 7)

(b) (− 13) + (+18)

(c) (− 10) + (+19)

(d) (− 250) + (+ 150)

(e) (− 380) + (− 270)

(f) (− 217) + (− 100)

Answer:

(a) 11 + (−7) = 4

(b) (−13) + (+18) = 5

(c) (−10) + (+19) = 9

(d) (−250) + (+150) = −100

(e) (−380) + (−270) = −650

(f) (−217) + (−100) = −317

Question 4:

(a) 137 and −354 (b) − 52 and 52

(c) − 312, 39 and 192 (d) − 50, − 200 and 300

Answer:

(a) 137 + (−354) = −217

(b) −52 + 52 = 0

(c) −312 + 39 + 192 = −312 + 231 = −81

(d) −50 + (−200) + 300 = −250 + 300 = 50

Question 5:

Find the sum:

(a) (− 7) + (− 9) + 4 + 16 (b) (37) + (− 2) + (− 65) + (− 8)

Answer:

(a) (−7) + (−9) + 4 + 16 = −16 + 20 = 4

(b) 37 + (−2) + (−65) + (−8) = 37 + (−75) = −38
