to push our intellect to accomplish tasks‚ we need only know how to operate what ever device the generations before us have created to help us with these tasks. In China for instance‚ the students are not aloud to use calculators to solve simple calculations all throughout schooling. Americans no longer are on a level playing field with China and a lot of other nations such as Bulgaria and Japan when it comes to mathematics. We as Americans would just as easily rather use the calculators for every
