How do you subtract whole numbers?
First, remember this:
- When subtracting
whole numbers, always work from right to left, and always subtract
the bottom number from the top number. Subtract the digits
in the ones
column first, then move on to the tens
column, and finally move on to the hundreds
column.
Example: First subtract the digits in the ones
column. Use the blocks beside the problem to help you understand.
