Before You Begin
Have a pen and paper ready. Attempt every practice problem by hand before checking the answer. Writing out each step builds the habit of showing and verifying your work.
Notation Safety
The rules for writing numbers safely are covered in Writing Numbers Safely in the Start Here section. Review that page before beginning if you haven't already.
