Three-Digit Subtraction #3 | Interactive Worksheet - Free Printable

Problem: Solve the three-digit subtraction problems.

The worksheet contains 12 subtraction problems, and we will solve each one step by step. Let's go through them systematically.

---

#### Problem 1:
$$
566 - 456
$$
- Subtract the ones place: \(6 - 6 = 0\)
- Subtract the tens place: \(6 - 5 = 1\)
- Subtract the hundreds place: \(5 - 4 = 1\)

$$
566 - 456 = 110
$$

---

#### Problem 2:
$$
199 - 182
$$
- Subtract the ones place: \(9 - 2 = 7\)
- Subtract the tens place: \(9 - 8 = 1\)
- Subtract the hundreds place: \(1 - 1 = 0\)

$$
199 - 182 = 17
$$

---

#### Problem 3:
$$
450 - 385
$$
- Subtract the ones place: \(0 - 5\) (borrow 1 from the tens place, making it \(10 - 5 = 5\))
- Subtract the tens place: \(4 - 1 = 3\) (after borrowing, \(5 - 8\) becomes \(14 - 8 = 6\))
- Subtract the hundreds place: \(4 - 3 = 1\)

$$
450 - 385 = 65
$$

---

#### Problem 4:
$$
962 - 249
$$
- Subtract the ones place: \(2 - 9\) (borrow 1 from the tens place, making it \(12 - 9 = 3\))
- Subtract the tens place: \(5 - 4 = 1\) (after borrowing, \(6 - 4 = 2\))
- Subtract the hundreds place: \(9 - 2 = 7\)

$$
962 - 249 = 713
$$

---

#### Problem 5:
$$
799 - 535
$$
- Subtract the ones place: \(9 - 5 = 4\)
- Subtract the tens place: \(9 - 3 = 6\)
- Subtract the hundreds place: \(7 - 5 = 2\)

$$
799 - 535 = 264
$$

---

#### Problem 6:
$$
630 - 283
$$
- Subtract the ones place: \(0 - 3\) (borrow 1 from the tens place, making it \(10 - 3 = 7\))
- Subtract the tens place: \(2 - 8\) (after borrowing, \(12 - 8 = 4\))
- Subtract the hundreds place: \(6 - 2 = 4\)

$$
630 - 283 = 347
$$

---

#### Problem 7:
$$
400 - 391
$$
- Subtract the ones place: \(0 - 1\) (borrow 1 from the tens place, making it \(10 - 1 = 9\))
- Subtract the tens place: \(9 - 9 = 0\) (after borrowing, \(0 - 9\) becomes \(10 - 9 = 1\))
- Subtract the hundreds place: \(4 - 3 = 1\)

$$
400 - 391 = 9
$$

---

#### Problem 8:
$$
759 - 256
$$
- Subtract the ones place: \(9 - 6 = 3\)
- Subtract the tens place: \(5 - 5 = 0\)
- Subtract the hundreds place: \(7 - 2 = 5\)

$$
759 - 256 = 503
$$

---

#### Problem 9:
$$
852 - 145
$$
- Subtract the ones place: \(2 - 5\) (borrow 1 from the tens place, making it \(12 - 5 = 7\))
- Subtract the tens place: \(4 - 4 = 0\) (after borrowing, \(5 - 4 = 1\))
- Subtract the hundreds place: \(8 - 1 = 7\)

$$
852 - 145 = 707
$$

---

#### Problem 10:
$$
596 - 371
$$
- Subtract the ones place: \(6 - 1 = 5\)
- Subtract the tens place: \(9 - 7 = 2\)
- Subtract the hundreds place: \(5 - 3 = 2\)

$$
596 - 371 = 225
$$

---

#### Problem 11:
$$
675 - 255
$$
- Subtract the ones place: \(5 - 5 = 0\)
- Subtract the tens place: \(7 - 5 = 2\)
- Subtract the hundreds place: \(6 - 2 = 4\)

$$
675 - 255 = 420
$$

---

#### Problem 12:
$$
661 - 526
$$
- Subtract the ones place: \(1 - 6\) (borrow 1 from the tens place, making it \(11 - 6 = 5\))
- Subtract the tens place: \(5 - 2 = 3\) (after borrowing, \(6 - 2 = 4\))
- Subtract the hundreds place: \(6 - 5 = 1\)

$$
661 - 526 = 135
$$
