Freeform mathematical computations
Abstract:
Freeform mathematical computations are described. In implementations, an input is recognized as a freeform selection of an area of a user interface output by a computing device. Text is identified that is associated with the area defined by the freeform selection and that includes one or more numbers. A mathematical computation is performed that involves the one or more numbers.
