# List of problems in mathematical notation

From Learning

This page gives a **list of problems in mathematical notation**. The list focuses on problems with the symbolism of mathematics rather than other communication problems/conventions (such as using "if" to mean "iff" in definitions, not introducing variables, etc.).

Name | Description | How to avoid |
---|---|---|

Overloading/abuse of notation | This happens when the same symbol is used for different purposes. For instance, parentheses are used to group expressions, for writing tuples, for function calls, in superscripts or subscripts with various meanings ( for the th derivative or the th function in some sequence), and so forth. The equals sign is often used for equality both in the object language and the metalanguage in mathematical logic, and used as part of the expression to define an event in probability. | |
