Two-Digit Subtraction with Renaming
Learning Objective
I can subtract two-digit numbers with renaming (borrowing).
Key Concepts
In the number 46, the digit 6 is in the ones place, and the digit 4 is in the tens place, representing 40.
When subtracting two-digit numbers, it is important to line up the place values correctly, with the ones place aligned and the tens place aligned.
When the ones digit in the top number is smaller than the ones digit in the bottom number, you need to regroup or borrow from the tens place to perform the subtraction.
