Arithmetic operator
An arithmetic operator is a programming-language operator that performs a numerical calculation on one or more operands.
Building User-Friendly DSLs
An operator that performs a numerical arithmetic calculation such as multiplication, division, addition, or subtraction.
- How it is used
- Orders arithmetic expression evaluation and guides implementation of expression evaluators.
- How deep it goes
- Explains recursive evaluation, parentheses, precedence, and AST construction, stopping short of broader operator semantics.
- Examples
- Uses 1 + 2 * 3 and 1 + 2 * (3 + 4) to demonstrate precedence and parentheses.
- What you can do after
- Evaluate arithmetic expressions recursively and represent their evaluation order with ASTs.

A CSS arithmetic operator is a symbol that performs addition, subtraction, multiplication, or division within a CSS mathematical expression.
- How it is used
- Calculates layout, size, and transformation values through CSS math functions.
- How deep it goes
- Defines four operators and explains syntax, units, scalar operands, and precedence, but defers detailed calc() treatment.
- Examples
- Uses width calculations, angle addition, unit validation, scalar division, and a table of operator results.
- What you can do after
- Apply it via calc() to construct valid CSS values with compatible units and predictable precedence.
