# OvrMathf

Description

This Node is responsible for implementing simple Mathematic operations between [OvrNumericVariables](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/variables/ovrnumericvariable.md).

#### Variable Compatibility

Based on the type of variables involved, some operations are not allowed:

* OvrInt and OvrFloat cannot be Added or Subracted to OvrVector2, OvrVector3 and OvrQuaternion, nor can be Multiplied or Divided to OvrQuaternion
* OvrQuaternion can only be Multiplied to OvrVector3 and OvrQuaternion

#### Attributes
