"Ten More and Ten Less" math worksheet for practicing addition and subtraction by tens.

The task involves finding numbers that are ten more or ten less than the given numbers. To solve this, we need to:

1. Add 10 to a number to find "ten more."
2. Subtract 10 from a number to find "ten less."

Let's solve each problem step by step.

---

Problem 1:

- Given: 34
- Ten more: \( 34 + 10 = 44 \)
- Ten less: \( 34 - 10 = 24 \)

Problem 2:

- Given: 46
- Ten more: \( 46 + 10 = 56 \)
- Ten less: \( 46 - 10 = 36 \)

Problem 3:

- Given: 72
- Ten more: \( 72 + 10 = 82 \)
- Ten less: \( 72 - 10 = 62 \)

Problem 4:

- Given: 56
- Ten more: \( 56 + 10 = 66 \)
- Ten less: \( 56 - 10 = 46 \)

Problem 5:

- Given: 81
- Ten more: \( 81 + 10 = 91 \)
- Ten less: \( 81 - 10 = 71 \)

Problem 6:

- Given: 39
- Ten more: \( 39 + 10 = 49 \)
- Ten less: \( 39 - 10 = 29 \)

Problem 7:

- Given: 17
- Ten more: \( 17 + 10 = 27 \)
- Ten less: \( 17 - 10 = 7 \)

Problem 8:

- Given: 20
- Ten more: \( 20 + 10 = 30 \)
- Ten less: \( 20 - 10 = 10 \)

Problem 9:

- Given: 55
- Ten more: \( 55 + 10 = 65 \)
- Ten less: \( 55 - 10 = 45 \)

Problem 10:

- Given: 84
- Ten more: \( 84 + 10 = 94 \)
- Ten less: \( 84 - 10 = 74 \)

Problem 11:

- Given: 63
- Ten more: \( 63 + 10 = 73 \)
- Ten less: \( 63 - 10 = 53 \)

Problem 12:

- Given: 19
- Ten more: \( 19 + 10 = 29 \)
- Ten less: \( 19 - 10 = 9 \)

Problem 13:

- Given: 48
- Ten more: \( 48 + 10 = 58 \)
- Ten less: \( 48 - 10 = 38 \)

Problem 14:

- Given: 25
- Ten more: \( 25 + 10 = 35 \)
- Ten less: \( 25 - 10 = 15 \)

Problem 15:

- Given: 87
- Ten more: \( 87 + 10 = 97 \)
- Ten less: \( 87 - 10 = 77 \)

Problem 16:

- Given: 93
- Ten more: \( 93 + 10 = 103 \)
- Ten less: \( 93 - 10 = 83 \)
