I am a semi-retired engineer just getting started on TPT and would like feedback on ideas such as this, so this is a FREE template of the full version. The template version has 5 completed questions and answers. You can cut, paste, and modify to complete the other 20 question slides, or you can opt for the full version for $2 with all 25 questions and worked out answers. Where applicable, units are carried through to show how a real-world problem would be completed. Math skills have served me well during a long career; all students should have fun with and appreciate the power of math.
