We are asked to **carry out the following calculations, expressing each result with the correct number of significant figures**:

**24.567 g + 0.044 78 g = ? g**

**Recall: **For addition and subtraction, look at the decimal portion (i.e., to the right of the decimal point) of the numbers ONLY.

**Here is what to do: **

- Count the number of significant figures in the decimal portion of each number in the problem. (The digits to the left of the decimal place are not used to determine the number of decimal places in the final answer.)
- Add or subtract in the normal fashion.
- Round the answer to the LEAST number of places in the decimal portion of any number in the problem.

Carry out the following calculations, expressing each result with the correct number of significant figures:

24.567 g + 0.044 78 g = ? g
