(f) (-2)+ 8 +(-4)

Answer:

(a) 9 + (-6) = 3

(b) 5 + (-11) = -6

(c) ( – 1) + ( – 7) = -8

(d) (-5) + 10 = 5

(e) ( – 1) + ( – 2) + ( – 3) = -6

(f) ( – 2) + 8 + ( – 4) = 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) = 11-7 = 4

(b) (-13)+ 18 = 5

(c) (-10)+ (+19) = -10+19 = 9

(d) (-250) + (+150) = -250 + 150 = -100

(e) (-380) + (-270) = -380 – 270 = -650

(f) (-217)+ (-100) = -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) = 137 – 354 = -217

(b) (-52)+ 52 = 0

(c) (-312)+ 39 +192

= -312 + 231 = -81

(d) (-50) + (-200) + 300

= -50 – 200 + 300 = -250 + 300 = 50

Question 5.

Find the sum:

(a) (-7) + (-9) + 4 + 16

(b) (37) + (-2) + (-65) + (-8)

Answer:
