C++ / LANGUAGE AND MATHEMATICS
ESINMATH
Turn mathematical notation into a structure a program can reason about.
01 / THE PROBLEM
Expressions become trees that can be evaluated and simplified.
A mathematical expression needs a clear grammar and representation before it can be evaluated, simplified or connected to variables and a user session.
02 / THE APPROACH
How the system fits together.
The C++ project tokenizes input, builds expression-tree structures and implements rational arithmetic. Its source includes expression simplification, variable handling and a session layer, supported by the course-provided ESIN libraries.
Input text → tokenization
Tokens → expression tree
Rational values → exact arithmetic
Tree operations → evaluation and simplification
Variables → interactive math session
03 / ENGINEERING DECISIONS
Preserve structure while simplifying
Expression nodes represent operations and operands, allowing simplification rules to operate over the expression rather than raw text alone.
Keep rational calculations exact
A separate rational type handles fraction arithmetic and its error cases alongside integer and real expression values.
