How do you ADD 24 grams and 0.012 grams in chemistry?

Question

You have to use Places Pass Decimal. So would it be 24 grams?

Answer 1

In addition, the sum can only have a number of decimal places equal to the least number of decimal places of the numbers added.
so
24 + 0.012 = 24.012
but since 24 had zero decimal places, you must round your answer to zero decimal places. So the answer becomes 24, just as if you added nothing.

The wonderful world of significant digits in science..

Answer 2

You add two numbers in chemistry just like you add two numbers in math.

24 + 0.012 = 24.012
