a) (-3) *(-2-10) -5:7 -9 = (-3) *(-12) - 5/7 -9= 36 - 5/7-9 = 35i7/7 - 9i5/7 = 26i2/7
b) (-2)^3 +45 : (-3)^2 = -8 +45 : 9 = -8 + 5 = -3
c) 15-(-2) *4 :(-11)+4 +5 -2 :2 -3= 15 -(-8) : (-11)+ 9 -1 -3 = 15 - 8/11 +5= 19i3/11
d) (-2) *1 - 4 :4 = -2 -1 = -3
e) 12 - 20 : 2 *3 = 12 - 10 * 3 = 12 -30 = -18
f) -8 +4 :3 * 6 :(-1) +3= -8 +4/3 *6 :(-1) +3= -8 +8 :(-1) +3 = -8 -8 +3 = -13
