11 - 25 = -14
14 - (-17) = 31

Explanation:

Step1: Solve 7 - 5

Subtract 5 from 7. $7 - 5 = 2$

Step2: Solve 25 - 24

Subtract 24 from 25. $25 - 24 = 1$

Step3: Solve (-19) - 1

Subtract 1 from -19. $(-19) - 1 = -20$

Step4: Solve (-15) - 12

Subtract 12 from -15. $(-15) - 12 = -27$

Step5: Solve 11 - 25

Subtract 25 from 11. $11 - 25 = -14$

Step6: Solve 14 - (-17)

Subtract a negative (which is addition). $14 + 17 = 31$

Step7: Solve 9 - (-15)

Subtract a negative (which is addition). $9 + 15 = 24$

Step8: Solve (-17) - 20

Subtract 20 from -17. $(-17) - 20 = -37$

Step9: Solve 19 + (-17)

Add a negative (which is subtraction). $19 - 17 = 2$

Step10: Solve 21 - 7

Subtract 7 from 21. $21 - 7 = 14$

Step11: Solve (-1) - 4

Subtract 4 from -1. $(-1) - 4 = -5$

Step12: Solve (-23) - 25

Subtract 25 from -23. $(-23) - 25 = -48$

Step13: Solve 6 - 24

Subtract 24 from 6. $6 - 24 = -18$

Step14: Solve 9 - (-25)

Subtract a negative (which is addition). $9 + 25 = 34$

Step15: Solve (-8) - 14

Subtract 14 from -8. $(-8) - 14 = -22$

Step16: Solve (-19) - (-22)

Subtract a negative (which is addition). $(-19) + 22 = 3$

Step17: Solve 17 - (-18)

Subtract a negative (which is addition). $17 + 18 = 35$

Step18: Solve (-15) - 12 (Wait, already did? Wait, no, (-15)-12 was step4. Wait, maybe I miscounted. Let's recheck. Wait, the problem has multiple rows. Let's list all:

First column (top to bottom):

1. $7 - 5 = 2$
2. $25 - 24 = 1$
3. $(-19) - 1 = -20$

Second column (top to bottom):

1. $(-15) - 12 = -27$
2. $11 - 25 = -14$
3. $14 - (-17) = 31$

Third column (top to bottom):

1. $9 - (-15) = 24$
2. $(-17) - 20 = -37$
3. $19 + (-17) = 2$

Fourth column (top to bottom):

1. $21 - 7 = 14$
2. $(-1) - 4 = -5$
3. $(-23) - 25 = -48$

Fifth column (top to bottom):

1. $6 - 24 = -18$
2. $9 - (-25) = 34$
3. $(-8) - 14 = -22$

Sixth column (top to bottom):

1. $(-19) - (-22) = 3$
2. $17 - (-18) = 35$

Wait, maybe the user wants specific ones? Let's pick a few more:

Seventh column (top to bottom):

1. $19 - (-19) = 38$ (Wait, original problem: 19 - (-19)? Wait, no, the first row middle: 19 - (-19) was written as 38? Wait, the handwritten says 19 - (-19) = 38? Wait, no, 19 - (-19) is 38? Wait, 19 +19=38. Yes.

Eighth column (top to bottom):

1. $19 - 5 = 14$ (handwritten)
2. $(-12) - (-9) = -3$ (handwritten)
3. $(-13) - 25 = -38$ (handwritten)

Ninth column (top to bottom):

1. $18 + (-22) = -4$? Wait, no, 18 + (-22) = -4? Wait, 18 -22=-4. But handwritten says 40? Wait, maybe 18 +22=40? Oh, maybe 18 - (-22)=40. Yes, 18 +22=40.
2. $(-24) - 15 = -39$ (handwritten)
3. $(-21) - (-12) = -9$ (handwritten)

Tenth column (top to bottom):

1. $14 - 17 = -3$ (top)
2. $8 + (-7) = 1$ (middle)

Wait, maybe I should solve all visible:
