            For a simple calculation, I rarely use the calculator. According to me, with the dependency calculator will make the brain so 'dull', because they are not trained regularly. How about you?

                    I RARELY ever use a calculator, when I was in high school I had the nick name of the human calculator because I am so good at mental math
Division Multiplication Addition and Subtraction Are all very easy for me with numbers into the 100 thousands.
