When adding or subtracting measured quantities what determines the number of decimal places?

I presume this is a question about scientific arithmetic.
When adding or subtracting two numbers, with a different number of decimal places, the quantity with the least number of decimal places determines the number of decimal places in the answer.
For example, let's say you are adding two masses:
.1 grams
.11 grams
.1grams + .11grams = .21 grams
Because .1 only has one decimal place, the answer becomes .2 grams, and we ignore the .01 because it is lost due to a lack of precision.
The process of multiplying and dividing is different, as you compare significant digits instead of decimal places instead.

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.
What are the three rules of adding and subtracting decimals for 5 grade?
line up the decimal point when your adding and subtracting. add annex a zero when you have extra number. sometimes you can use a number line.
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...
Why are significant figures used and how are significant figures obtained?
Significant figures are used to receive a more accurate number. To obtain the number you you multiply or divide the quantities, leave as many significant figures in the answer as there are in the quantity with the least number or significant figures. If adding or subtracting quantities, leave the same number of decimal places in the answer as there are in the quantity with the least number of decimal places
How do you separate a number from it's decimal numbers?
With scissors? Or try subtracting the decimal away!
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 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 is it important to align decimal point when adding or subtracting decimal numbers?
Because if you dont , your answer will be a whole number and that will make your answer wrong

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.
