The scientific calculators will be used every day by students in all of my math classes. We are currently using the basic solar powered Casio HS-10. This calculator is difficult to use especially when students are working on multi-step problems that involve long calculations. Students often times get frustrated with the calculator because if they type in the wrong number in the middle of a calculation they have to clear the calculator and retype all the steps. Since a majority of my students need Business Math to graduate, a decent calculator is necessary. Having these 25 scientific calculators will improve my students' chances of completing their math credits and graduating.
