(a) (–7) – 8 – (–25)
(b) (–13) + 32 – 8 – 1
(c) (–7) + (–8) + (–90)
(d) 50 – (–40) – (–2)

SOLVE ​

Answer 1

a) (– 7) – 8 – (– 25)

= -7 -8+25

=-7 + 17

= 10

b) -13 + 32 - 8 -1

= -13 + 13 + 19 - (8+1)

=19 - 9

= 10

c) -7 + (-8) + (-90)

= -15+(-90)

= 105

d) 50 - (-40) - (-2)

= 50 - (-40 - 2)

= 50 + 42

= 92
