    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
