(−42) + 27 = - 15

(−2) ⋅ 3 − 56 :(−8) = - 6 - (-7) = 1

(−2) ⋅ (−7) = 14

(−27) − (−35) = - 27 + 35 = 8

(−6) ⋅ 4 = - 24

36 :(−6) ⋅ (−3) = - 6 * (-3) = 18

(−14) + (−76) = - 90

72 :(−8) = - 9

7⋅(−12) - (−16) + (-12) : (-3) = - 84 - (-16) + 4 = 84 + 16 + 4 = 104

(−12) − 39 = - 51

38 + (−15) = 18

(−63) :(−9) = 7

34 − 47 = - 13
