Ответ:

Пошаговое объяснение:

7-(-3) = 7+3 = 10

12-(-4) = 12+4 = 16

4+(-8) = 4 - 8 = -4

12-(-9) = 12+9 = 21

2) -5+(-7) = -(5+7) = -12

-8-(-13) = -8 + 13 = 5

-5+(-15) = -5 - 15 = -(5+15) = -20

-12+(-6) = -12 - 6 = -(12+6) = -18

17+(-4) = 17 - 4 = 13

3) -15-(-37) = -15 + 37 = 22

-48-(-16) = -48 + 16 = -32

16-(-87) = 16 + 87 = 103

-17-(-46) = -17 + 46 = 29

-19+(-57) = -19 - 57 = -(19+57) = -76

4) -304-166 = -(304+166) = -470

540-(-239) = 540+239 = 779

726-596 = 130

-663+202 = -461

281-435 = -154

Answer 3

Let's calculate the given expressions one by one:

1. 7 - (-3) = 7 + 3 = 10
2. 12 - (-4) = 12 + 4 = 16 4 + (-8) = 4 - 8 = -4 12 - (-9) = 12 + 9 = 21 -5 + (-7) = -5 - 7 = -12 -8 - (-13) = -8 + 13 = 5 -5 + (-15) = -5 - 15 = -20 -12 + (-6) = -12 - 6 = -18 17 + (-4) = 17 - 4 = 13
3. -15 - (-37) = -15 + 37 = 22 -48 - (-16) = -48 + 16 = -32 16 - (-87) = 16 + 87 = 103 -17 - (-46) = -17 + 46 = 29 -19 + (-57) = -19 - 57 = -76
4. -304 - 166 = -470 540 - (-239) = 540 + 239 = 779 726 - 596 = 130 -663 + 202 = -461 281 - 435 = -154

Here are the results for each expression:

1. 10
2. 16, -4, 21, -12, 5, -20, -18, 13
3. 22, -32, 103, 29, -76
4. -470, 779, 130, -461, -154
