Inspired by FormulaPro for the TI-Nspire and a want to improve my past Customizable Formula Solver, I have created an improved program. I am pleased to release Custom Formula Pro. It is written in TI-Basic and is compatible for both monochrome and color calculators. The program can be customized to fit almost any set of formulas.
