Hai everyone. This is my proposed new logo for N+ calculator. I hope you like it. I used Sketchup software and photoshop. N+ Calculator is an open source android learning app that helps you to solve equations, systems of equations, polynomial, derivative, integral and limit. The calculator also provides the features to solve problems in algebra, analytics,trigonometry, determination of statistics. Some other features includes; prime factors, Modulo, Catalan number, and Fibonacci number. However the calculator doest not show the steps to solve equations, system of equations, derivative,etc...but only show the final result. The computer an work in two modes; decimal mode (for example 0.123123123123), and fraction mode for result with arbitrary precision (for example 9^99999).
