Line 2:
Create a program which parses and evaluates arithmetic expressions.
* An [[wp:Abstract_syntax_tree|abstract-syntax tree]] (AST) for the expression must be created from parsing the input.
* The AST must be used in evaluation, also, so the input may not be directly evaluated (e.g. by calling eval or a similar language feature.)
Line 9:
* Precedence-control parentheses must also be supported.
;Note:
* Parentheses
* Multiplication/Division (left to right)
* Addition/Subtraction (left to right)
