Advanced Calculator

This npm acts as a scientific calculator and allows you to do many calculations without worrying about formulas.

This module is still under work. My ambition is to get all basic to intermediate to advanced mathematical formulas for Statistics, Vectors, Probability, Complex Numbers, and much more! Please see the methods working so far below:

Installation

npm install advanced-calculator

Please refer each section's detailed screenshots for it's formulas for better understanding
