Answer 2

Question:

Compute each of the following:

(a) 30 + (-25) + (-10)

(b) (-20) + (-5)

(C) 70 + (-20) + (-30)

(d) -50 + (-60) + 50

(e) 1 + (-2) + (-3) + (-4)

(f) O + (-5) + (-2)

(g) 0-(-6) – (+6)

(h) 0-2-(-2)

ANSWER:

________________

a) 30 + (-25) + (-10)

=> 30 - 25 - 10

=> 5 - 10 = -5

so, answer is -5

________________

b) (-20) + (-5)

=> -20 - 5

=> -25

so, answer is -25

________________

c) 70 + (-20) + (-30)

=> 70 - 20 - 30

=> 50 - 30 = 20

so, answer is 20

________________

d) -50 + (-60) + 50

=> -50 - 60 + 50

=> -110 + 50 = -60

so, answer is -60

________________

e) 1 + (-2) + (-3) + (-4)

=> 1 - 2 - 3 - 4

=> -1 - 6 = -7

so, answer is -7

________________

f) 0 + (-5) + (-2)

=> 0 -5 -2

=> -7

so, answer is -7

________________

g) 0 - (-6) - 6

=> 0$\bold{ \cancel{+ 6}\cancel{ -6}}$

=> 0

so, answer is 0

________________

h) 0 - 2 - (-2)

=> 0 $\bold{ \cancel{-2}\cancel{ +2}}$

=> 0

so, answer is 0
