Printable math worksheet featuring basic addition and subtraction exercises for learning.

Let’s solve each math problem one by one. We’ll go row by row, left to right.

Row 1:
- 1 + 1 = 2
- 5 + 7 = 12 (5 + 5 = 10, then +2 more = 12)
- 10 - 4 = 6 (count back 4 from 10: 9,8,7,6)
- 10 + 9 = 19 (10 + 10 = 20, minus 1 = 19)

Row 2:
- 7 + 4 = 11 (7 + 3 = 10, +1 more = 11)
- 9 - 4 = 5 (take away 4 from 9: 8,7,6,5)
- 18 - 9 = 9 (half of 18 is 9)
- 7 + 2 = 9

Row 3:
- 9 - 2 = 7
- 8 + 4 = 12 (8 + 2 = 10, +2 more = 12)
- 8 - 2 = 6
- 12 - 8 = 4 (8 + 4 = 12, so 12 - 8 = 4)

Row 4:
- 13 - 6 = 7 (6 + 7 = 13)
- 7 - 4 = 3
- 8 + 6 = 14 (8 + 2 = 10, +4 more = 14)
- 2 + 3 = 5

Row 5:
- 9 - 5 = 4
- 8 + 10 = 18
- 13 - 3 = 10
- 8 + 9 = 17 (8 + 10 = 18, minus 1 = 17)

Row 6:
- 1 + 9 = 10
- 18 - 8 = 10
- 12 - 10 = 2
- 17 - 9 = 8 (9 + 8 = 17)

Row 7:
- 9 + 8 = 17 (same as above)
- 11 - 7 = 4 (7 + 4 = 11)
- 13 - 5 = 8 (5 + 8 = 13)
- 10 + 6 = 16

Row 8:
- 17 - 10 = 7
- 3 + 6 = 9
- 9 - 8 = 1
- 9 + 1 = 10

Row 9:
- 2 + 10 = 12
- 14 - 7 = 7 (7 + 7 = 14)
- 8 - 1 = 7
- 9 + 10 = 19

Row 10:
- 4 - 1 = 3
- 10 - 1 = 9
- 4 + 8 = 12 (4 + 6 = 10, +2 more = 12)
- 18 - 10 = 8
