Example
Subtracting Across Zeros: 4,701 − 4,462 = ___
Answer: 239
Not quite. The answer is
💡 Ones: 4 is less than 6, so regroup 1 from the hundreds (the zeros in between become 9s). Now 14 − 6 = 8. Tens: the 0 is now 9. 9 − 9 = 0. Hundreds: the 1 is now 0. 0 is less than 6, so regroup 1 from the thousands. Now 10 − 6 = 4. Thousands: the 7 is now 6. 6 − 3 = 3. So 7,104 − 3,696 = 3,408.
✓ Correct!

💡 How to solve: Subtracting Across Zeros
When the digit you need to borrow from is 0, keep moving left until you reach a digit that is not 0. Borrow 1 from it, and every 0 you passed becomes 9; the column you started in gets 10 more. Example: 5,003 − 1,876. The ones need to borrow, but the tens and hundreds are 0. Borrow from the 5 thousands: 5,003 becomes 4 thousands, 9 hundreds, 9 tens and 13 ones. Now subtract: 13 − 6 = 7, 9 − 7 = 2, 9 − 8 = 1, 4 − 1 = 3. So 5,003 − 1,876 = 3,127. A quick trick: 5,003 − 1,876 is the same as 5,002 − 1,875 (take 1 from both), and that needs no borrowing across zeros.

💡 Ones: 3 + 0 = 3. Tens: 0 + 6 = 6. Hundreds: 7 + 2 = 9. Thousands: 4 + 3 = 7. So 4,703 + 3,260 = 7,963.
✓ Correct!

💡 Ones: 3 + 0 = 3. Tens: 0 + 6 = 6. Hundreds: 7 + 2 = 9. Thousands: 4 + 3 = 7. So 4,703 + 3,260 = 7,963.
💡 How to solve: Adding 4-Digit Numbers
Write the numbers in columns with ones under ones, then add one column at a time from the right. When a column makes 10 or more, write the ones digit and carry the 1 to the next column. Example: 4,768 + 2,595: ones 8 + 5 = 13, write 3 carry 1; tens 6 + 9 + 1 = 16, write 6 carry 1; hundreds 7 + 5 + 1 = 13, write 3 carry 1; thousands 4 + 2 + 1 = 7. So 4,768 + 2,595 = 7,363.

💡 Ones: 7 − 1 = 6. Tens: 9 − 3 = 6. Hundreds: 6 − 2 = 4. Thousands: 3 − 2 = 1. So 3,697 − 2,231 = 1,466.

💡 How to solve: Multi-Digit Addition & Subtraction (Mixed Review)
Line up the numbers by place value. Start at the ones and move left, carrying when a column adds to 10 or more, and borrowing from the next place when you need to subtract a bigger digit.

💡 Ones: 9 − 2 = 7. Tens: 4 − 2 = 2. Hundreds: 4 − 2 = 2. Thousands: 7 − 6 = 1. So 7,449 − 6,222 = 1,227.

💡 How to solve: Subtracting 4-Digit Numbers
Write the bigger number on top and line up the places. Subtract one column at a time from the ones. If the top digit is smaller than the bottom digit, borrow 1 from the next column to the left: it becomes 10 more in this column. Example: 7,352 − 2,687: ones 2 < 7, borrow: 12 − 7 = 5; tens 4 < 8, borrow: 14 − 8 = 6; hundreds 2 < 6, borrow: 12 − 6 = 6; thousands 6 − 2 = 4. So 7,352 − 2,687 = 4,665. Check by adding: 4,665 + 2,687 = 7,352.

💡 Taking the same amount from both numbers keeps the gap between them the same. Ones: 9 − 4 = 5. Tens: 9 − 1 = 8. Hundreds: 3 is less than 8, so regroup 1 from the thousands. Now 13 − 8 = 5. Thousands: the 6 is now 5. 5 − 3 = 2. So 6,399 − 3,814 = 2,585.

💡 The missing number is how much was taken away, so subtract the answer from 5,603. Ones: 3 is less than 5, so regroup 1 from the hundreds (the zeros in between become 9s). Now 13 − 5 = 8. Tens: the 0 is now 9. 9 − 6 = 3. Hundreds: the 6 is now 5. 5 is less than 6, so regroup 1 from the thousands. Now 15 − 6 = 9. Thousands: the 5 is now 4. 4 − 1 = 3. So 5,603 − 1,665 = 3,938. Check: 5,603 − 3,938 = 1,665.
