Math Keyboard 1.7.35

The keyboard features a well-organized division into various key groups, enhancing user experience and functionality. The Criteri-R key group is specifically designed to support the Criteri-R application, while the User key group empowers users to customize their preferred key texts, similar to macros.

In addition to standard mathematical input keys, the keyboard includes several mutable keys. These mutable keys offer flexibility by allowing users to modify their contents and map them to any keys within the selected key group. The User key group is particularly beneficial, enabling users to define numerous keys according to their individual needs. This adaptability makes the Math Keyboard compatible not only with Criteri-R, but also with other applications such as Excel, WolframAlpha, and more.

The keyboard also provides the capability to access superscript and subscript variations for available characters by using the Shift key. This feature accommodates advanced mathematical notation and enhances clarity in expression.

Furthermore, users have the option to expand their character set through in-app purchases, which include arithmetical symbols, Greek letters, arrows, brackets, and various mathematical constructs. A preview of these additional characters is available on the device prior to completing any purchase.

To fully utilize its features after installation, it is essential to enable and select Math Keyboard in the System Settings.
