Why do you line up the decimal points when adding and subtracting?
you have to line up the decimal points because you need to keep each place value in the same column so when you add or subtract you wont make any errors
Why is it important to line up the decimal points when adding or subtracting but not when multiplying?
Because when adding or subtracting, the operations must take account of the place values of individual digits in the numbers. When multiplying, only the overall order of magnitudes are relevant for placing the decimal point in the product.
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.
When adding or subtracting decimals the decimal point must be in line for all numbers?
Yes.
When adding or subtracting decimal how can you be sure to add or subtract only digits that have the same place value?
The simplest way is to line up the numbers so that their decimal points are aligned, and corresponding digits are also aligned according to their place value.

Unlike addition, there is no need to line up the decimal points. Just multiply ignoring the decimal points. When you are done, move the decimal point of the result to the left equal to the number of digits after the decimal point for both multiplicands.
