a) 5 * (4+7) - 6*3 = 5*11 -18 = 55 - 18 = 37
b) 2 * 9:3 + 12 * (17 - 4*3) = 2*3 + 12*(17 - 12) = 6 + 12*5 = 6+ 60 = 66
c) 2 * 70 - (3*5 + 14) * 2 - 10 = 140 - (15+14) * 2 - 10 = 140 -29 * 2 - 10 = 140 - 58 -10 = 140 - 68 = 72
d) (8*7 - 6² : 3) * 9 = (56 - 36:3) * 9 = (56 - 12) * 9 = 44 * 9 = 396
e) 72 - 6 : (4*7 - 9²:3) = 72 - 6 : (28 - 81:3) = 72 - 6 : (28-27) = 72 - 6:1 = 72-6 = 66
f) (7-5)³ * (7² - 6²) = 2³ * (49-36)= 8 * 7 = 56
g) 3 * 90 - [9 * (81 - 68) ] = 270 - (9 * 13) = 270 - 117 = 153
h) (60000 - 14052) : 48 = 45948 : 48 = 957,25
i) 1000 : [(475 + 245) : 72] = 1000 : (720 : 72) = 1000 : 10 = 100
j) 3996 : 74 + 3780 : 35 = 54 + 108 = 162
k) 149 * (6864 : 88) = 149 * 78 = 11622
