{mathtools} is an extension package to amsmath. It provides bugfixes and adds useful tools for mathematical typesetting.

The mathtools package is an extension package to amsmath. There are two things on mathtools’ agenda:

  1. correct various bugs/deficiencies in amsmath until these are fixed by the AMS, and
  2. provide useful tools for mathematical typesetting, be it a small macro for typesetting a prescript or an underbracket, or entirely new display math constructs such as a multlined environment.
