Effects of Calculators on StudentsPositive effects on students who know basic

mathMore fun, able to do more problems w/ less

errors learn how to do more calculator

functionsNegative effects on students who do not

know basic math become dependent on calculators

Area of InteractionHuman Ingenuity- Why do we create things?The calculator was created to make

mathematical functions easier. It was also created to do more functions with more numbers than the Abacus.
