Significant Figures vs Periodic Table & Chem Balancer

Significant (symbolic) numbers are the digits used to represent the modified number. Only the landmark farthest to the right is uncertain. The farthest right digit has a certain error in value, but it is still significant. Exact numbers have an exactly known value. There is no error or uncertainty in the value of the correct number.
