Question

-2-5+14= 8-9-1= -7-(-2)+5= 8-(-3)-6= 9-(-2)+7= 8-10-2= 9-(-2)-9= 7-9+3= -6-7-2= -8+9-2= Помогите пж.Эти дела с минусами.

Answer 1

=-7+14=7
=-1-1=-2
=-5+5=0
=11-6=5
=11+7=18
=-2-2=-4
=11-9=2
=-2+3=1
=-13-2=-15
=1-2=-1

Answer 2

Давайте рассмотрим каждое уравнение поочередно:

1. \(-2 - 5 + 14\): \(-2 - 5 + 14 = -7 + 14 = 7\)

2. \(8 - 9 - 1\): \(8 - 9 - 1 = -1 - 1 = -2\)

3. \(-7 - (-2) + 5\): \(-7 + 2 + 5 = -5\)

4. \(8 - (-3) - 6\): \(8 + 3 - 6 = 5\)

5. \(9 - (-2) + 7\): \(9 + 2 + 7 = 18\)

6. \(8 - 10 - 2\): \(8 - 10 - 2 = -4\)

7. \(9 - (-2) - 9\): \(9 + 2 - 9 = 2\)

8. \(7 - 9 + 3\): \(7 - 9 + 3 = 1\)

9. \(-6 - 7 - 2\): \(-6 - 7 - 2 = -15\)

10. \(-8 + 9 - 2\): \(-8 + 9 - 2 = -1\)

Итак, ответы на каждое уравнение:

1. \(-2 - 5 + 14 = 7\) 2. \(8 - 9 - 1 = -2\) 3. \(-7 - (-2) + 5 = -5\) 4. \(8 - (-3) - 6 = 5\) 5. \(9 - (-2) + 7 = 18\) 6. \(8 - 10 - 2 = -4\) 7. \(9 - (-2) - 9 = 2\) 8. \(7 - 9 + 3 = 1\) 9. \(-6 - 7 - 2 = -15\) 10. \(-8 + 9 - 2 = -1\)
