Three Digit Subtraction with Regrouping Worksheets - Free Printable

Problem: Solve the 3-digit subtraction problems and identify the largest and smallest answers.

#### Step-by-Step Solution:

We will solve each subtraction problem step by step, starting from the ones place, then the tens place, and finally the hundreds place. Let's go through each problem:

---

#### Problem 1: \( 472 - 236 \)
1. Subtract the ones: \( 2 - 6 \). Since 2 is less than 6, borrow 1 from the tens place (7 becomes 6).
- \( 12 - 6 = 6 \)
2. Subtract the tens: \( 6 - 3 = 3 \)
3. Subtract the hundreds: \( 4 - 2 = 2 \)

Answer: \( 472 - 236 = 236 \)

---

#### Problem 2: \( 594 - 273 \)
1. Subtract the ones: \( 4 - 3 = 1 \)
2. Subtract the tens: \( 9 - 7 = 2 \)
