Odpowiedź:
a) 6 + 9 + 100 = 115 | 30 - 12 + 70 = 88 | 50 - 40 + 24 = 34 | 7 * (1500 - 110) = 7 * 1390 = 9730 | b) 1.1 + 1.6 + 0.9 = 3.6 | 1.9 - 0.09 + 1.5 = 3.31 | 12.5 - 0.24 + 0.6 = 12.86 | 0.14 * 1.5 + 0.3 = 0.51 | 13 + 8 + 20 = 41 | 11 + 16 -25 = 2 | (120 + 90) : 10 = 21 | 2000 - (450 + 900) = 650 | 2.4 + 0.4 + 1.1 = 3.9 | 2.2 - 1.3 - 0.06 = 0.84 | 10 (1.2 + 0.32) - 2,5 = 12.7 | (0.08 + 0.26) : 0.04 = 8.5
