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.

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.

Add the two numbers, and divide the result by 2.

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

The numbers before the decimal points add to 48 so any numbers greater than 0 after the decimal makes the sum greater than 48

To the left of a decimal point are whole numbers. On the right of a decimal point are parts of a whole number.

If there are any numbers which are integers and so do not have a decimal point, then append one at the extreme right. Then arrange all the numbers in a column, with their decimal points aligned. Ad up the numbers ignoring the decimal points entirely. In the answer insert a decimal point under the column of decimal points.

no, they add to 10.10 To add decimal numbers you add like any other problem and bring down the decimal point

explain why it is important to line up decimal numbers by their place value when you add or subtract them

Put the numbers in a column with the decimal points aligned. Add the numbers ignoring the decimal points. Insert the decimal point in the answer exactly below the column of decimal points in the numbers being added (summands).

This is true for adding and subtracting ALL numbers, not just decimal representations.

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.

The only decimals that are integers are ones such as 4.00000 or -5.00 or 100.0. If there is anything other than 0 after the decimal place it is NOT an integer. So to add them, just add the numbers to the left of the decimal place.

You line up the numbers 55.85+555.95=n Then you add normal and you bring the decimal straight down 55 555.95 55.85 611.80

Add, subtract, multiply and divide.

Write the numbers in a column so that all the decimal points are one below the other. Put a decimal point in the answers underneath the coumn of decimal points. Then add the numbers ignoring the decimal points.

To add decimal numbers you line up the decimal points... _0.88 +0.035 --------- _0.915
