Microsoft Mathematics (formerly Microsoft Math) is a freely downloadable educational program, designed for Microsoft Windows, that allows users to solve math and science problems. Developed and maintained by Microsoft, it is primarily targeted at students as a learning tool.^[1]

A related freeware add-in, called Microsoft Mathematics Add-In for Word and OneNote, is also available from Microsoft and offers comparable functionality (Word 2007 or higher is required).^[2][3]

Microsoft Math has received 2008 Award of Excellence from Tech & Learning Magazine.^[4]
