__Objectives:__

- Determine the difference of a decimal and a whole number.
- Determine the difference of two multi-digit decimals that requires multiple regrouping.

__What is a decimal?__

A decimal is a number that has a whole number part separated by with a decimal point from the fractional part.

__What does it mean to "borrow"?__

Also known as "regrouping", we will "borrow" when we are subtracting two one-digit numbers where the top digit in a column is smaller than the bottom digit in the same column. For example, let's look at the difference of two one-digit numbers, 4 and 7. This would be 4 - 7. Since 4 is smaller than 7, we will need to "borrow" from the top digit in the column to the left. After borrowing, 4 - 7 would become 14 - 7. Now we can determine the difference since 14 is greater than 7. Now, let's look at an example below!

__The Difference of a Decimal and a Whole Number__
