a)
(-46 + 32 ) = -14
b)
19-25 = -6
c)
(-34)+(-56) = -90
d)
(-24)-35 = -59
e)
(-18)-(-24) = 6
f)
(- 2 1/3) *(-1 2/7) = (-7/3) * (-9/7) = 63/21 = 3
g)
(-12 2/3 ) : 3 1/6 = (-38/3) : 19/6 = (-38/3) * 6/19 = -228/57 = -4
(-46+32)= -14
19-25= -6
(-34)+(-56)= -34-56= -90
(-24)-35= -59
(-18)-(-24)= -18+24=6
(-2i1/3)*(-1ii2/7)= -7/3*(-1i2/7)= -7/3*(-9/7)= -(-7/3*9/7)= -(-3)=3
(-12i2/3):3i1/6= - 38/3:3i1/6= - 38/3:19/6= -4
