# Big operators

Variable-sized operators such as sums and integrals.

https://texform.dev/latex/topics/big-operators

This topic has 18 symbols from the base and ams packages. Symbols are single characters and are not render-tested, so they carry no support level. Entries are ordered by how often they appear in corpus formulas.

Packages: base (17), ams (1).
