The Wolfram Language uses a large number of original algorithms to provide automatic systemwide support for inequalities and inequality constraints. Whereas equations can often be solved in terms of numbers, even representing solution sets for inequalities is only made possible by the Wolfram Language's symbolic capabilities.


Less (<)  ▪  Greater (>)  ▪  LessEqual (<=)  ▪  GreaterEqual (>=)  ▪  Equal (==)  ▪  Unequal (!=)  ▪  Between  ▪  ...
