            Guide for the Tokens:
            integer and real: numbers
            identifier: variable, argument or parameter - never number or constant
            constant: e, pi, i, infinity, never identifier
            plus, minus, multiplication, division, modulo, power: arithmetic operators between operands
            factorial, transpose, inverse: postfix operators
            determinant: prefix operator
            leftParen, rightParen: expression grouping only
            equal: equations and definitions
            lessThan, lessThanOrEqual, greaterThan, greaterThanOrEqual, notEqual: comparisons
            functionApplication: function definition and call, encodes name and arguments
            derivative, partialDerivative, integral, gradient, jacobian: calculus operators and ther expression
            sum, product: represents the capital sigma or pi notation
            limit: limit notation
            matrix, vector: structured containers
            equationSystem, constrainedSystem: systems of relations or equations
