What else can I help you with?
When do you need to write zero as a placeholder when adding and subtracting decimals?
Adding decimal same as adding whole numbers
What happens to the decimal in adding and subtracting decimals?
When you are adding and subtracting decimals, youare +/- ing the whole numbers and tenths in the number. the decimal might go away ex: 1.3-0.3=1 or it won't ex: 1.9-0.3=1.6
What is the rule for significant figures when adding or subtracting decimals?
When adding and/or subtracting, your answer can only show as many decimal places as the measurement having the fewest number in the decimal places.
When adding or subtracting decimals always do what?
First you write the decimals one under the other, in such as way that the decimal points are aligned.
How are adding subtracting decimals different from multiplying them?
They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.

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.

Do decimal points need to be lined up when adding and subtracting decimals?
Yes, unless you are an expert.
What is the first step when you are adding and subtracting decimals?
Write them one above the other with the decimal points aligned.
When subtracting or adding numbers in scientific notation why do the exponents need to be the same?
This is effectively the same as lining up the decimal points when adding or subtracting ordinary decimal fractions.
Why do you line up the decimal when adding or subtracting decimal numbers?
Yes, When Adding and Subtracting decimals you should line up the decimals. You need to keep each place value in the same column, the same as when you add whole numbers you keep the ones column lined up, same for the tens, etc. Lining up the decimal points makes sure that the tenths column is kept together, same for the hundredths, and so on.
When multiplying decimals with whole numbers do you line up the whole numbers?
Hey awesome Question. The answer is no you do not have to line up the decimals when multyping only when adding and subtracting. The main thing is when you multiply make sure you put the decimal in the right place in your answer. YOu count how may places their are behind the decimals in BOTH numbers then you make sure their are that many places behind the decimal in you answer. :)
When do you line up the decimal?
you only line the decimals up when you are subtracting or adding not when you are multiplying im not sure about division...
