GED Skill: Adding and Subtracting Decimals
Adding and subtracting decimals is similar to adding and subtracting whole numbers. However, when you add or subtract decimals, it is important that you line up the decimal points. Once your numbers are lined up properly, you can add or subtract just like you would whole numbers.
Problem: Sally went to the store and purchased a can of soda for 75 cents and a bag of chips for $3.99. She gave the cashier a $10 bill. How much change will Sally get back?
Answer: $00.75 + $3.99 = $4.74
$10.00 - $4.74 = $5.26(change)
