Formularium program
Builded with interpreted basic, back in 1988/89, this program maintained a database of formulas. As user inputed the units and values, the inference motor searched the database and outputed all possible cross-link calculations.
This program had no graphical interface and no tools for database load. Leaving to the programmer (me) the task of initializing the database and load it with all decompositions of every formula entered.
MathCore project
Mathcore and some related project prototypes, for computer manipulation of algebraic symbols, in all of those projects there was no user expression input and the projects where tested with code wired expressions.
Those projects were all at an experimental fase, there I have fine tuned the needed object structure for symbolic manipulation.
Achived a certain degree in resolution/solving i needed an editor, this need leaded me to the current project.

Some output sample of MathCore (text output)

Resolution of 2*x/3=x*4, isolating x

Resolution of E=R*I, isolating R

Resolution of a*x+x/b=0, isolating x
