Answer 1

Answer:

56 + 23 + (-5)

you want to expand the bracket first

23 + (-5)

23-5 = 18

56 + 18 = 74

a) 74

6 + 24 + (-2)

24 - 2= 22

6 + 22 = 28

b) 28

3 + 7 + (-42)

7 - 42 = -35

3 - 35 = -32

c)-32

( 8 + 1 ) + (-3)

+(-3) = -3

9 - 3 = 6

d)6

( 7 + 10 ) + ( 3 + 1 )

17 + 4 = 21

e)21

59 + 2+ (-6)

2+(-6) = 2-6 = -4

59-4

55

f)55

41 + ( -89)

41 - 89

= - 48

g)-48

( - 13) + 33

-13+33

= 20

h) 20
