Question 1 (10 points)
a) 17 -8 x 2 + 3 x 4 = 17 - (8 x 2) + (3 x4) = 17 - 16 + 12 = 1 + 12 = 13 Rép: 13
b) 14 -3 + 24 ÷ 3 x 2 = 14 - 3 + (24 ÷ 3) x 2 = 14 - 3 + (8 x 2) = 14 - 3 + 16 = 11 + 16 = 27 Rép: 27
c) (4 + 8) ÷ 2 + (13 - 3) x 5 = 12 ÷ 2 + (13 -3) x 5 = (12 ÷ 2) + (10 x 5) = 6 + 50 = 56 Rép : 56
d) -72 + 14 x (-3) = -72 + (14 x -3) = -72 + -42 = -114 Rép: -114
e) -21 + [(-2 - 7) x 3 - (24 - 4) x 2] = -21 + [(-9 x 3) - (20 x 2)] = -21 + (-27) - 40 = -88 Rép: -88
