Answer 1

Explicație pas cu pas:

5+[7+3×(7-2)]:2-6=

5+ (7+3×5)÷2-6=

5 +(7+15)÷2-6

5+22:2-6=

5+11-6=

16-6=10

9+8×[7+6×(5+4×3)-2×1]-10×10=

9+8×[7+6×(5+12)-2]-100=

9+8×(7+6×17-2)-100=

9+8x(7+102-2)-100=

9+8×107-100=

9+856-100=

865-100= 765

[(36-36:2×0)+(6×7-4×9)]:7=

[(36-18×0)+(42-36)]:7=

(36-0+6):7=

42÷7= 6

(9 x 8 + 13): [5 x 4: (3 + 2) + 1]=

(72+13):[(20:5)+1]=

85: (4+1)=

85:5 = 17

6 + 3 x [18:3-3x (12:3-3)]: 9=

6 + 3 x [6-3x (4-3)]: 9=

6+3×(6-3×1):9=

6+3×(6-3):9=

6 +3×3:9=

6+ 9÷9=

6+1=7

2+2 x [2 +2:2 x (2 + 2 x 2)]=

2+2 x [2 +1 x (2 + 4)]=

2+2×(2+1×6)=

2+2×(2+6)=

2+2×8=

2+16=18
