Mathematics is the father of all sciences. Human beings need mathematics to calculate, evaluate, and integrate different aspects of science. We cannot survive without mathematics, and its uses whether it may be a thing as basic as paying the bill in a restaurant to a little specific thing like calculation of profit and loss, to a far more complex calculation of partial differential equation having ten or more independent variables to solve a complex physical behavior in environment. The use of calculators in solving mathematical problems has become a need of time as nowadays researchers are becoming more complex and to solve mathematical equations by hand has become impossible. It is now needed to develop methods which can provide us with quick and accurate results of mathematical problems with precision. The need of calculators is essential to analyze different complex problems and how they will affect our life. We need calculators to physically see the behavior of processes and observe their decline and increase as they change.
