задание за но у меня их два умаля время поджимает​

1.-28:7+8*(-9)+63=-13

2.20:(-33-4*(-7))-47=-51  

3.(-66+58-13):7*(-10)= 30 

4.15:(-3)+8*(26-31) =0.125

1. –28 : 7 + 8 · (–9) + 63  = -13

1) -28:7 = -4

2) 8*(-9) = -72

3) -4-72 = -76

4) -76+63 = -13

2. 20 : (–33 – 4 · (–7)) – 47 =  -51

1) 4*(-7) = -28

2) -33+28 = -5

3) 20:(-5) = -4

4) -4-47 = -51

3. (–66 + 58 – 13) : 7 · (–10)  = 30

1)  -66+58 = -8

3) -21:7 = -3

4) -3*(-10) = 30

4. 15 : (–3) + 8 · (26 – 31)  = -15

1) 15:(-3) = -5

2) 26-31 = -5

3) -5+8 = 3

4) 3*(-5) = -15

5. –30 : (–2 + (–10) · 6 + 52) =  3

1) (-10)*6 = -60

2) -2-60 = -62

3) -62+52 = -10

4) -30:(-10) = 3

6. 6 –19 + 7 · (–13 – 10 : (–2))  = -55

1) 10:(-2) = -5

2) -13+5 = -8

3) 7*(-8) = -42

4) -19-42 = -61

5) 6-61 = -55

7. –14 + 30 : (–5) · 10 – (–47)  = -27

1) 30:(-5) = -6

2) -6*10 = -60

3) -14-60 = -74

4) -74+47 = -27

8. 8 · (–3) : (+71 – 67) – 19  = -25

1) 8*(-3) = -24

2) 71-67 = 4

3) -24:4 = -6

4) -6-19 = -25

9. 3 · (–12 + 12 : 2) – 35  = -53

1) 12:2 = 6

2) -12+6 = -6

3) 3*(-6) = -18

4) -18-35 = -53

10. 14 : (54 – 61) · 3 – 28  = -34

1) 54-61 = -7

2) 14:(-7) = -2

3) -2*3 = -6

4) -6-28 = -34
