# Math

Incari has several **Nodes** for performing functions relating to *exponentiation*. They all take two *known* parameters and return the 3rd *unknown* value. These **Nodes** are:

* [**Power**](https://docs.incari.com/incari-studio/2.0/toolbox/math/power) - Multiplies the *base* value, against itself, a number of times defined by the *exponent*.
* [**Root**](https://docs.incari.com/incari-studio/2.0/toolbox/math/root) - Calculates the *nth root* of a *base* value, where *n* is defined by the *degree*.
* [**Logarithm**](https://github.com/cgi-studio-gmbh/incari-doc/tree/66656c2442958de634bc73f77b533a03f83df0fb/toolbox/math/logarithm.md) - Calculates the *exponent* to which the *base* value needs to be raised, to yield the input value.
