Quick explanation:
Brief explanation: To subtract two numbers, we align them vertically by place value and subtract each column starting from the right, borrowing when necessary.
Step-by-step solution:
- Step 1: Subtract the ones column: 4 - 2 = 2.
- Step 2: Subtract the tens column: 2 - 3. Since 2 is less than 3, we borrow from the hundreds place. The 7 in the hundreds place becomes 6, and the 2 becomes 12. 12 - 3 = 9.
- Step 3: Subtract the hundreds column: 6 - 5 = 1.
