Why is it important to align the decimal points when adding?
It reduces the chance of making errors.
How do you find the sum of decimal numbers?
You align their decimal points. Sum the numbers as normal and, in the answer, place the decimal point so that it lines up with those of the summands.
Why do you need to line up the decimal points when subtracting?
It is not a matter of aligning the decimal points, but aligning the place value columns so that the ones are under each other, the tens are under each other, the tenths are under each other, etc which is the proper way to subtract. As the decimal points are between the ones and tenths columns, with those place value columns aligned, the decimal points are aligned.Aligning the decimal points is an easy way to remember to align the place value columns, as with the decimal points aligned all the place value columns are automatically aligned.
Why do you line up decimals when do you add or subtract numbers?
You are lining up the place value columns, so that the tens are under each other, the ones are under each other, the tenths are under each other, the hundredths are under each other, etc so that when you do the addition/subtraction you are adding/subtracting the tens from the tens, the ones from the ones, the tenths from the tenths, the hundredths from the hundredths, etc. The easiest way to line up the place value columns is to align the decimal points. Remember that an empty place value column is the same as that place value column containing a zero. When adding/subtracting whole numbers align the numbers at their right hand end. What you are doing is actually aligning the "hidden" decimal points - the decimal point sits between the ones place value column and the tenths place value column; when there is no decimal part of a number, the decimal point (and trailing zeros) are not written, so it is "hiding" after the last (ones) digit of the number.
How do you plus decimals?
Treat them exactly like you would adding up whole numbers but align all the columns so that the decimals points are all in line/column and carry this point (and its position) down into the answer. 077.2 033.05 110.91 -------- 221.16

How do you place the decimal points in addends?

How do you align decimals when multiplying?
You do not need to align decimal points when multipylng. You multiply the two numbers ignoring the decimal point but ensuring that any trailins 0s are present. The number of digits after the decimal point in the answer is the sum of the number of digits after the decimal points in the two multiplicands.
What is a decimal tabs?
It is a tab that is used to align decimal points. When you set a decimal tab and hit the tab key, as you type it will align numbers around the decimal point. As soon as you type a decimal point, the decimal point will stay fixed under the tab. It is particularly handy when numbers have different amounts of decimal places.
Which operations require you to align numbers using their decimal points before you begin a calculation?
Addition and subtraction.
Why is it important to line up decimals?
It is irrelevant if multiplying or dividing decimal numbers. For addition and subtraction it is not sufficient: you need to line up the decimal points as well as the digits according to their place values. If you intend to simply align the decimal points then you may as well not bother. This is to ensure that addition or subtraction is carried out for digits with the same place value.
Why is it better to right align numbers?
So the decimal points line up and you can have a visual clue that larger numbers are longer.
