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.
How do you solve this problem .41 plus 21.4 plus 6.3 plus 280 step by step?
Here is one way: Add the first two numbers; add the result to the third number; add the result of this to the fourth number.However, to do the addition with pencil and paper, it is best to write the numbers down, one below the other, keeping the decimal points aligned. Then add from the right to the left.Here is one way: Add the first two numbers; add the result to the third number; add the result of this to the fourth number.However, to do the addition with pencil and paper, it is best to write the numbers down, one below the other, keeping the decimal points aligned.

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
