Desmos is an advanced graphing calculator implemented as a browser application and a mobile application. As of September 2012, it had received around 1,000,000 US dollars of funding from Kapor Capital, Learn Capital, Kindler Capital, Elm Street Ventures and Google Ventures.[1] In addition to graphing both equations and inequalities, it also features lists, plots, regressions, interactive variables, graph restriction, simultaneous graphing, piecewise function graphing, polar function graphing, two types of graphing grids — among other computational features commonly found in a programmable calculator. It can also be used in several different languages.[2][3][4]

Users can create accounts and by doing so can save the graphs and plots that they have created. A permalink can then be generated which allow users to share their graphs and elect to be considered for staff picks. The tool comes pre-programmed with 35 different graphs for the purpose of teaching new users more about using the tool, or even about the mathematics involved.

A modified version of the calculator has been used in standardized tests, such as the State of Texas Assessments of Academic Readiness test.[5] Moreover, activity modules for classrooms can also be created through a teacher account.
