(c)(-87)+(-54)+(-12)
(d) 143+(-18)+(-230)
(b) 97+(-45)+(-73)​

Answer 1

Step-by-step explanation:

$(a) \: \: \: 68 + ( - 90) + ( - 12) \\ = 68 - 90 - 12 \\ = \underline{ \underline{ - 34}} \\ \\ (b) \: \: \: 97+(-45)+(-73) \\ = 97 - 45 - 73 \\ = \underline{ \underline{ - 21}} \\ \\ (c) \: \: \: (-87)+(-54)+(-12) \\ = - 87 - 54 - 12 \\ = \underline{ \underline{- 153}} \\ \\ (d) \: \: \: 143+(-18)+(-230) \\ = 143 - 18 - 230 \\ = \underline{ \underline{- 105}}$
