Ответ:
-34+67+(-19)+(-44)+34 = $-34+34-19-44+67 = -63$
6+(-7)(-15)-(-6)-30 = $6+105+6-30 = 87$
7+(-8)-(-12)-(-7)+12-20 = $7+8+12+7+12-20 = 26$
3 1/6 + (-2 5/9)-(-1 7/12) = $3\frac{1}{6}-2\frac{5}{9}+1\frac{7}{12} = \frac{19}{6}-\frac{23}{9}+\frac{19}{12} = \frac{38}{12}-\frac{41}{12}+\frac{38}{12} = \frac{35}{12}$
