PHYSICS: Did you remember sig figs? All this SI and calculations stuff will come back to you before you know it. Holler if we need to practice..

When you multiply or divide, the number in the problem with the fewest sig figs determines the number of sig figs in the answer. When you add/subtract, the number in the problem with the lowest decimal value determines the place of the last sig fig in the answer. And remember, you never go by counting numbers or conversion factors. Don’t forget to show all your work!
