1. Calculează, respectând ordinea efectuării operațiilor:
a) (35 : 5 + 7 x 29): 2 + [250 - (38 x 2 x 1 + 9)} = (2+203):
b) [(357 : 7 + 344:8): 2] x 31 + 17 - (500:4 + 7) =
c) (30 x 5 + 30): 10 + 639:9- [25 x (39 - 10 x 2)]​

Answer 1

Răspuns:

20-2×4+9×6=

20-8+54=66

40÷2-5×3+81÷9=

20-15+9=14

(42×2-48÷2)÷10=

(84-24)÷10=

60÷10=6

(32-10×3)×(0÷9+50)=

(32-30)×(0+50)=

2×50=100

(10×7+2)÷8-9×(6-6÷6)÷9+2×2×2×2=

(70+2)÷8-9×(6-1)÷9+2×2×2×2=

72÷8-9×5÷9+2×2×2×2=

9-5+16=20

[(2×9÷3+45÷5÷3)+(55÷5+5-3+2)]+88÷8×3=

[(6+3)+(11+4)]+88÷8×3=

(9+15)+88÷8×3=

24+88÷8×3=

24+33=57
