- * Leibnitz notation, the standard representation for Calculus
- * Big O notation, used for example in analysis to represent less significant elements of an expression, to indicate that they will be neglected
- * Z notation, a formal notation for specifying objects using Zermelo-Fraenkel set theory and first-order predicate logic
- Systems to represent very large numbers
- * Conway chained arrow notation
- * Knuth's up-arrow notation

Typographical conventions
- Infix notation for representing calculations in an almost linguistic format, such as a+b-c
- Polish notation or prefix notation, which places the operator before the operands, such as + a b
- Reverse Polish notation or postfix notation, which places the operator after the operands, such as a b +
- Numeral systems, notation for writing numbers, including
- * Positional notation also known as place-value notation, like our decimal system in which the meaning of a digit depends on its place in a number.
- * sign-value notation such as Roman numerals. Before the sexagesimal system standardized ancient numbers, dozens of different sign-value number systems were used. Different cities and different trades used different sign-value notation.
- * binary notation, a positional notation in base two.
- * octal notation, a positional notation in base eight, used in some computers.
- * decimal notation, a positional notation in base ten.
- * hexadecimal notation, a positional notation in base sixteen, commonly used in computers.
- * sexagesimal notation, an ancient numeral system in base sixty.
- * scientific notation for expressing large and small numbers.
