These results will be used in my project determining whether or not playing an instrument has an effect on math scores. 1. NO calculators or any other aid are allowed on this quiz. (you may use a sheet of paper to work out your problems on. )2. Take as much time as you need. 3. Do your best! I'm not going to judge you if you don't know the answers. (:4. Your identity will remain anonymous in the project. However, please tell me your grade level and whether or not you play an instrument. 5. Place spaces between terms. (i. E. 5 + 4 = 9 NOT 5+4=9 ) This is vital for your scoring!6. Use carats (^) for powers. (i. E. X squared is x^2, x cubed is x^3, etc. )7. Put fractions in parentheses. (i. E. Three-fourths is (3/4) NOT 3/4. )8. Please remember that this quiz is volunt
