Calcule en respectant les règles de priorité dans les opérations.
- 5 x 9 : 3 + 7 = 15 + 7 = 22
- 5 x (25 : 5 + 3) = 5 x (5 + 3) = 5 x 8 = 40
- 18 : 6 – 5 = 3 – 5 = -2
- (36 : 3 + 6 ) : 2 = (12 + 6) : 2 = 18 : 2 = 9
- (18 – 8 + 10) x 3 + 7 = 20 x 3 + 7 = 60 + 7 = 67
- 18 – 3 x 2 + 6 = 18 – 6 + 6 = 18
- 700 : 5 : 7 x (140 – 40) = 20 x 100 = 2000
- 8 + 2 x 9 : 3 – 7 = 8 + 6 – 7 = 7
- (13 – 6) x 2 x (16 – 6) = 7 x 2 x 10 = 140
- 25 x 3 : 5 – 6 = 15 – 6 = 9
- 12 – 18 : 2 + 7 = 12 – 9 + 7 = 10
- 18 – (6 – 4) + [9 – (11 – 5)] x 2 = 18 – (6 – 4)+ [9 – 6] x 2 = 18 – 2 + 3 x 2 = 18 – 2 + 6 = 22
- 35 : 5 + 5 x 3 – (4 + 6 : 6) = 35 : 5 + 5 x 3 – (4 + 1) = 35 : 5 + 5 x 3 – 5 = 7 + 15 – 5 = 17
- 7 x 3 + 7 x 6 – 27 : 9 = 21 + 42 – 3 = 60
- (56 : 7 + 10) x (6 – 3) + 9 = (8 + 10) x 3 + 9 = 18 x 3 +9 = 54 + 9 = 63
