Answer 1

40 : 8 + 2 · 100 = 5 + 200 = 205

100 - (40 + 36) : 4 = 100 - 76 : 4 = 100 - 19 = 81

900 : 9 - 6 · 10 = 100 - 60 = 40

40(8 + 2) · 100 = 40 · 10 · 100 = 40 · 1000 = 40000

(100 - 40 + 36) : 4 = (60 + 36) : 4 = 96 : 4 = 24

600 : 100 + 50 · 10 = 6 + 500 = 506

(40 : 8 + 2) · 100 = (5 + 2) · 100 = 7 · 100 = 700

100 - (40 + 36 : 4) = 100 - (40 + 9) = 100 - 49 = 51

70 · 5 + 3 · 100 = 350 + 300 = 650

Answer 2

40 : 8 + 2 * 100 = 205

1) 40 : 8 = 5

2) 2 * 100 = 200

3) 5 + 200 = 205

40 * (8 + 2) * 100 = 40 000

1) 8 + 2 = 10

2) 40 * 10 = 400

3) 400 * 100 = 40 000

600 : 100 + 50 * 10 = 506

1) 600 : 100 = 6

2) 50 * 10 = 500

3) 6 + 500 = 506

(40 : 8 + 2) * 100 = 700

1) 40 : 8 = 5

2) 5 + 2 = 7

3) 7 * 100 = 700

100 - (40 + 36) : 4 = 81

1) 40 + 36 = 76

2) 76 : 4 = 19

3) 100 - 19 = 81

(100 - 40 + 36) : 4 = 24

1) 100 - 40 = 60

2) 60 + 36 = 96

3) 96 : 4 = 24

100 - (40 + 36 : 4) = 51

1) 36 : 4 = 9

2) 40 + 9 = 49

3) 100 - 49 = 51

900 : 9 - 6 * 10 = 40

1) 900 : 9 = 100

2) 6 * 10 = 60

3) 100 - 60 = 40

70 * 5 + 3 * 100 = 650

1) 70 * 5 = 350

2) 3 * 100 = 300

3) 350 + 300 = 650

Answer 3

40:8 = 5 2*100 = 200 So, the first equation becomes: 5 + 200 = 205

40 + 36 = 76 76:4 = 19 100 - 19 = 81 So, the second equation becomes: 81

900:9 = 100 6*10 = 60 So, the third equation becomes: 100 - 60 = 40

8 + 2 = 10 10 * 100 = 1000 So, the fourth equation becomes: 1000

40:8 = 5 2 + 5 = 7 7 * 100 = 700 So, the fifth equation becomes: 700

100 - 40 = 60 36:4 = 9 60 + 9 = 69 So, the sixth equation becomes: 69

600:100 = 6 50 * 10 = 500 So, the seventh equation becomes: 6 + 500 = 506

40:8 = 5 2 + 5 = 7 7 * 100 = 700 So, the eighth equation becomes: 700

100 - 40 = 60 36:4 = 9 60 + 9 = 69 So, the ninth equation becomes: 69

70 * 5 = 350 3 * 100 = 300 So, the tenth equation becomes: 350 + 300 = 650

Therefore, the solutions to the given equations are: 205, 81, 40, 1000, 700, 69, 506, 700, 69, 650.
