a) 25 + 6 × 8 = 25 + 48 = 73

b) 42:7 + 72:8 = 6 + 9 = 15

c) 45 + 32:4 - 25 = 45 + 8 - 25 = 53 - 25 = 28

d) 25 + 819×5 = 25 + 4095 = 4120

e) 64,8 × 4 + 53 = 259.2 + 53 = 312.2

f) 36 - 6×6 + 12:3 + 63,73 = 36 - 36 + 4 + 63,73 = 4 + 63,73 = 67,63

g) 100 - 5×10 + 32:8 + 5 + 4:4 = 100 - 50 + 4 + 5 + 1 = 60

h) 8×6 - 28:4 + 3x3x3 -9x1 = 48 - 7 + 27 - 9 = 59

i) 2×8 + 4×4 + 3×6 - 48:8 + 6×7 = 16 + 16 + 18 - 6 + 42 = 86

k) 7×7 + 6×6 - 5×5 - 4×4 - 3×3 = 49 + 36 - 25 - 16 - 9 = 35
