This tool defines relations that all high school and college students would recognize as mathematical equations. They consist of a left hand side (lhs) and a right hand side (rhs) connected by the relation operator "=".

This tool applies operations to both sides of the equation simultaneously, just as students are taught to do when attempting to isolate (solve for) a variable. Thus the statement Equation/b yields a new equation Equation.lhs/b = Equation.rhs/b

The intent is to allow using the mathematical tools in SymPy to rearrange equations and perform algebra in a stepwise fashion using as close to standard mathematical notation as possible. In this way more people can successfully perform algebraic rearrangements without stumbling over missed details such as a negative sign. This mimics the capabilities available in SageMath and Maxima, but can be installed in a generic python environment.

Once the algebra is complete it is possible to substitute numbers with units into the solved equation to calculate a numerical solution with proper units.

Setup/Installation: Use pip to install in your python environment: python pip -U Algebra_with_SymPy To use in a running python session issue the following command : from algebra_with_sympy import *. This will also import the SymPy tools. If you want to isolate this tool from the global namespace you are working with change the import statement to import algebra_with_sympy as spa, where spa stands for "SymPy Algebra". Then all calls would be made to spa.funcname().

Usage examples can be found in the docstrings and the demonstration Jupyter notebook Demonstration of equation class.ipynb in this git repository.
