How is adding and subtracting decimals similar to and different from adding and subtracting whole numbers?
You write down the numbers you want to add and subtract, making sure the decimal points are aligned. Then, you add (or subtract) EXACTLY as you would add or subtract integers. The decimal point in the solution should be aligned with the decimal points in the original numbers.
What are two decimal numbers that when you subtract the difference is 16.825.?
Let the two decimal numbers be x and y. We can set up the equation x - y = 16.825. To find two numbers that satisfy this equation, we can choose any value for x and then subtract 16.825 to find y. For example, if we let x = 20, then y = 20 - 16.825 = 3.175. Therefore, the two decimal numbers are 20 and 3.175.
How do you do add and subtract decimals?
How To Add/Subtract DecimalsTo add decimals you HAVE TO LINE UP THE DECIMAL POINTS and then add the numbers up (Tip: when your first starting if the decimals don't go to the same place value you can add as may zeros at the END of the decimal. This does NOT change the place value)After you have added up the digits you "drop" the decimal point down.Example 105.43+23.4=?105.43+23.40-----------128.83To subtract decimals it's the same thing as adding YOU MUST LINE UP THE DECIMALS. You would subtract as you normally would.You would then "drop" down the decimal point.Example 109.783-43.39=?109.783-43.390----------66.393
