The operators described in this section are defined using regular Anselme functions and can be redefined or overloaded. For example, `1+1` is equivalent `_+_(1, 1)`. For a detailled description of what these operators do by default, look at the [standard library](standard_library.md) documentation.

`_+_`, `_-_`, `_*_`, `_/_`, `_//_`, `_%_`, `_^_` are intended to be used as addition, substraction, multiplication, division, integer division, modulo, and exponentiation respectively. `_+_`, `_-_`, `_*_`, `_/_`, `_%_`, `_^_` are intended to be used as addition, substraction, multiplication, division, modulo, and exponentiation respectively.
`-_` and `+_` are intended to be used as the negation and positive prefixes. `-_` and `+_` are intended to be used as the negation and positive prefixes.
