Significant Figures and Arithmetic Rules

Significant figures and significance arithmetic rules have been summarized and explained through pedagogical tests. Starting with simple questions and moving toward more complex ones. You can simply answer each question by reading its corresponding hint (or previous hints) without any further background. Finally, you can just review the Hints for the final exam. This would be very useful for students taking chemistry or physics courses to understand and review this topic. Other chapters for general chemistry will be soon published.
