9. Active Learning Assignment:
On your handout,
Fill in the first columns of blanks as to how you would type it into the calculator.
Use a * for mult., / for div., ^ for powers, etc.
Find the answer in the second blank.
If you have to finish at home, you should have a calculator (any scientific calculator) to find the answers (4 dec. pl.)
You will hand it in next time I see you and it will be for a grade.
