b - 63 : 21 + 11 x 2/3 = 63 : 21 + 11 x 8 = 3 + 88 = 91
c - 25 - 35 : (71 - 64) + 321 = 25-35 : 7 + 123 = 25 - 5 + 123 = 20 + 123 = 143
d- 8 x (365 - 255) :8 - 8 x 13 = 8 x 90 : 8 - 8 x 13 = 720 : 8 - 8 :13 = 90 - 8 x 13 =
= 90 - 104 = -14 ( nie wiem czy dobrze )
e- (49 + 23) : 12 x 24 = 72 : 12 x 24 = 6 x 24 = 144
f- 56 : ( 102 - 98) +86 = 56 : 4 +86 = 14 + 86 = 100
g - (89 + 19) : (73-64) + 2^3 = (89 + 19) : (73 - 64) + 8 = 108 : 9 = 12
h- 4^3 - (125-97) x 2 +72 = 64 - (125 - 97) x 2 +72 = 64-28 x 2 +72 = 64 - 56 + 72 = 8 + 72 = 80
