Question

1.Calculează:
(8x9 – 4:2)-(91-9x9) =
100-(27+ 7x6 -48:8):7 = 1
(4x8 + 3x9 +21):10: (40 – 9x4) =
56:(100 – 8x5 – 6x5 – 7x3 -1) =
9:00 am
(24+ 6x2):4 +7 –(28 - 12:3):6=
8740
(54: 6x3 - 6x2): 3 =
(2x3x3):2x(45:9 +72:8 - 16:2)=​

Answer 1

Răspuns:

(8×9-4:2)-(91-9×9)=(72-2)-(91-81)=70-10=60

100-(27+7×6-48:8):7=1

100-(27+42-6):7=1

100-63:7=1

100-9=1

91=1

(4×8+3×9+21):10:(40-9×4)=

(32+27+21):10:(40-36)

80:10:4=

8:4=

(24+6×2):4+7-(28-12:3):6=8740

(24+12):4+7-(28-4):6=8740

36:4+7-24:6=8740

9+7-4=8740

12=8740

(54:6×3-6×2):3

(9×3-12):3

(27-12):3

15:3
