Math Expression includes tools to evaluate mathematical expressions.

Mathematics Expression is a written arrangement of symbols following the context dependent, syntactic conventions of mathematical notation. Symbols can denote numbers (constants), variables, operations, and functions. Other symbols include punctuation marks and brackets, used for grouping where there is not a well defined order of operations. Expressions are commonly distinguished from formulas: expressions are a kind of mathematical object, whereas formulas are statements about mathematical objects. This is analogous to natural language, where a noun phrase refers to an object, and a whole sentence refers to a fact. For example 8x - 5 is an expression, while the inequality 8x - 5 > 3 is a formula.

A formal expression is a kind of string of symbols, created by the same production rules as standard expressions, however, they are used without regard to the meaning of the expression. In this way, two formal expressions are considered equal only if they are syntactically equal, that is, if they are the exact same expression. For instance, the formal expressions "2" and "1+1" are not equal.
