MathBrush is an intuitive system that recognizes mathematical expressions as you draw them. It recognizes a wide range of mathematics, including polynomials, integrals, and matrices. The MathBrush app, available on iPad and iPhone, offers many features to provide the best experience for entering and manipulating handwritten mathematics. Through the MathBrush app you can save your mathematical expressions, share them, manipulate them, or export them for a document or a web page. MathBrush exports LaTeX, MathML and image formats. MathBrush also allows you to manipulate the expression using a Computer Algebra System (CAS) by applying operations and getting results. The manipulation results can also be shared in different formats.

Handwriting Math

Using the MathBrush app, you can draw a mathematical expression and the typeset form of the recognized expression is displayed for quick feedback. MathBrush offers intuitive gestures to facilitate the editing of the expression and to provide a great user experience. MathBrush supports scratchout for deleting ink, pinch for zooming in and out, circle to select part of the ink, and press and hold to move the selected part of the ink or the whole ink expression. Refer to the Guide for detailed information and video tutorials.

Recognition Correction

Instead of re-writing parts of the expression that are misrecognized, MathBrush offers recognition alternatives for symbols and sub-expressions for you to choose from.

Latex and MathML

MathBrush generates the Latex and MathML of the ink expression. From settings, you can choose to copy MathML, Latex or Both. Use the copy button (circled) to copy the expression and you can paste it in any other App, document or web page.

User's Profile

For better recognition results, you can train the recognizer to accept certain ways of drawing some symbols by providing multiple samples of those symbols. Save the training samples in a profile and use it as your active profile. Multiple profiles can be stored and one of them can be activated at any time.

Manipulation

MathBrush allows you to manipulate input expressions using the Sage Computer Algebra System and obtain results. You can also manipulate the resulted expressions. For each expression, MathBrush dynamically generates the available operations based on the type of the expression. MathBrush also supports 2D and 3D plotting of expressions.

Sharing Content

MathBrush allows you to share the input expression and/or the manipulation results through email, airdrop or any available App based on the type of data you choose to share. You can share a picture, latex, MathML or the MathBrush format. If you choose to attach the MathBrush file format, the receiver can open the attachment using the MathBrush app and continue working on the file. You can also save images of the input expression and/or the manipulation results in your photo library.

Settings

You can change the settings in MathBrush to personalize its look and behaviour.

Available Products

MathBrush offers in-app purchase for sharing the expressions and for unlimited expression sizes. For expressions manipulation, MathBrush provides a free trial period after which you can choose to subscribe to the feature.

Organize MathSheets

MathBrush allows you to create multiple notebooks to better organize your MathSheets. You can share multiple sheets from a notebook, delete MathSheets or a whole notebook. On the iPad, you can also move a MathSheet to another notebooks.

Help

You can use the help option within the app for quick tips on using the MathBrush app and for best user experience.
