Of course! Let's solve each subtraction problem on the "Sporty Subtraction" worksheet. The goal is to subtract the second number from the first number in each equation.

Here are the solutions, row by row:

---

Row 1:
- 20 - 2 = 18
(Start at 20, count back 2: 19, 18)
- 19 - 7 = 12
(Start at 19, count back 7: 18, 17, 16, 15, 14, 13, 12)

Row 2:
- 18 - 2 = 16
(18 minus 2 is 16)
- 12 - 5 = 7
(12 minus 5 is 7 — you can think of it as 12 - 2 = 10, then 10 - 3 = 7)

Row 3:
- 16 - 4 = 12
(16 minus 4 is 12)
- 20 - 9 = 11
(20 minus 9: take away 10 and add 1 back → 10 + 1 = 11)

Row 4:
- 12 - 4 = 8
(12 minus 4 is 8)
- 17 - 3 = 14
(17 minus 3 is 14)

Row 5:
- 9 - 6 = 3
(9 minus 6 is 3)
- 15 - 6 = 9
(15 minus 6: you can think 15 - 5 = 10, then 10 - 1 = 9)

Row 6:
- 11 - 4 = 7
(11 minus 4: 11 - 1 = 10, 10 - 3 = 7)
- 13 - 8 = 5
(13 minus 8: 13 - 3 = 10, 10 - 5 = 5 — or just count up from 8 to 13: 9,10,11,12,13 → that’s 5 steps)
