Rules for Significant Figures
1. Non-zero numbers do count.
2. Zeros between numbers do count.
3. Zeros to the right of the decimal, to the right of a number do count.
4. Zeros in front of numbers do not count.
5. Zeros to the left of the decimal only count if they are in between a number and the decimal.
When multiplying or dividing, your answer has the same number of significant figures as the number in the
problem with the least number of significant figures.
When adding or subtracting, your answer has the same number of decimal places as the number in the problem
with the least number decimal places.
