Solve the Subtraction: 92443 minus 74526 in Vertical Format

Q: What happens to the digit I borrow from?

When you borrow 1 from a digit, that digit decreases by 1. So if you borrow from 4, it becomes 3. Remember to use this new reduced value in your next calculation!

Q: How do I keep track of all the borrowing?

Work column by column from right to left. Write small numbers above digits when you borrow to help remember the changes. Take your time - accuracy is more important than speed!

Q: What if I need to borrow from a zero?

When borrowing from 0, you need to 'borrow from the borrow' - keep moving left until you find a non-zero digit, then work your way back right, turning each 0 into 9.

Step-by-step solution

Let's solve the subtraction problem $92443 - 74526$ .

Step-by-step Vertical Subtraction:

Align the numbers, so each digit is in the correct place (thousands, hundreds, tens, units).
$\begin{array}{c} \phantom{1}92443 \\ -74526 \\ \end{array}$
Subtract starting from the rightmost digit (units place). If the digit in the minuend is smaller, borrow from the next digit to the left.

Units: $3 - 6$ requires borrowing. Borrow from the next digit (4 becomes 3), making it $13 - 6 = 7$ .
Tens: $3 - 2 = 1$ (after borrowing adjustment).
Hundreds: $4 - 5$ requires borrowing. Borrow from the next digit (4 becomes 3), making it $14 - 5 = 9$ .
Thousands: $3 - 4$ requires borrowing. Borrow from the next digit (9 becomes 8), making it $13 - 4 = 9$ .
Ten thousands: $8 - 7 = 1$ (after borrowing adjustment).

Therefore, the result of the subtraction $92443 - 74526$ is: $17917$ .

Final Answer

17917

Key Points to Remember

Essential concepts to master this topic

Place Value Alignment: Stack digits in proper columns for accurate calculation
Borrowing Technique: When $3 - 6$ is impossible, borrow 1 from tens place
Verification: Add your answer to the subtrahend: $17917 + 74526 = 92443$ ✓

Common Mistakes

Avoid these frequent errors

Forgetting to adjust borrowed digits
Don't subtract from the original digit after borrowing = wrong result! When you borrow 1 from the tens place (4 becomes 3), you must use the reduced digit for the next calculation. Always reduce the borrowed digit and use that new value.

FAQ

Everything you need to know about this question

Why do I need to borrow when the top digit is smaller?

You can't subtract a larger number from a smaller one and get a positive result. Borrowing lets you 'take' 10 from the next column, making $3$ become $13$ so you can subtract!

What happens to the digit I borrow from?

When you borrow 1 from a digit, that digit decreases by 1. So if you borrow from 4, it becomes 3. Remember to use this new reduced value in your next calculation!

How do I keep track of all the borrowing?

Work column by column from right to left. Write small numbers above digits when you borrow to help remember the changes. Take your time - accuracy is more important than speed!

Can I check my answer without adding?

Yes! You can also count up from the smaller number to the larger: $74526 + ? = 92443$ . The missing amount should equal your subtraction answer.

What if I need to borrow from a zero?

When borrowing from 0, you need to 'borrow from the borrow' - keep moving left until you find a non-zero digit, then work your way back right, turning each 0 into 9.
