(c)(-7) + (-8) + (-90)
(d) 50- (-40)-(-2)​

Answer 1

Step-by-step explanation:

(a) (-7) -8 – (-25) (-7) – 8 – (-25) = (-7) – 8 + 25 = -15 + 25 = 10 (b) (-13) + 32 – 8 – 1 (-13) + 32 – 8 – 1 = -13 + 32 – 8 – 1 = 32 – 22 = 10 (c) (-7) + (-8) +(-90) (-7) + (-8) + (-90) = -7 – 8 – 90 = -105 (d) 50 – (-40) – (-2) 50 – (-40) – (-2) = 50 + 40 + 2 = 92
