Microsoft Math, a math solving app developed by Microsoft, has been removed from the iPhone and Android app stores. The app allowed users to input math problems directly or use its camera to recognize problems and provide step-by-step solutions and answers. Although the app has been removed from the stores, users who have already installed it can still use it to solve math problems, except for the handwriting recognition feature. The web version of the app is still available for use. According to reports, the app was removed due to unknown reasons, but its functionality remains available on the web.
