Answer 1

Answer:

4

a) -217

b) 0

c) -81

d) 50

5

a) 4

b) -38

Step-by-step explanation:

4

a) 137+(-354)

=137-354

= -217

b) -52+52

= 52-52

= 0

c) -312+39+192

= -392+231

taking ( - ) common

= -(312-231)

= -81

d) -50+(-200)+300

= (300-200)-50

= 100-50

= 50

5

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

= -7-9+4+16

taking ( - ) common

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

= -16+20

= 20-16

= 4

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

= 37-2-65-8

taking ( - ) common

= 37- (2+65+8)

= 37- (65+8+2)

= 37- (65+10)

= 37- 75

taking ( - ) common

= -(-37+75)

= -(75-37)

= -38
