# Subtracting multi-digit numbers

### Subtracting multi-digit numbers

In this lesson, we will learn:

• How to subtract examples with regrouping: from two 2-digit numbers up to two 6-digit numbers
• How to subtract three numbers
• How to regroup when there are zeroes

Notes:

• If you need to borrow when subtracting:
• 1 ten can be regrouped ("exchanged") for 10 ones
• 1 hundred can be regrouped for 10 tens
• 1 thousand can be regrouped for 10 hundreds
