The Quatriceps API by Tetragy Limited enables developers to make requests to receive instructional output for various mathematical operations; currently, five operations are supported with the help of the xlop LaTeX package. Setup kits for Drupal and WordPress simplify installation for non-developers. Tetragy is a software company that focuses on mathematics education and computing.
Quatriceps provides custom mathematical problems and their solutions at a significantly lower cost than Wolfram Alpha or an in-house solution. Tetragy is working to add new operations; the latest to be added computes and displays the method to find the least common multiple of two integers. The company will work with developers to create custom operations to suit their organization.
