In OneNote for Windows 10 or OneNote Online, you have the option to turn the Math feature On or Off.  The Math feature is a tool for teachers and students that helps break down a math equation step-by-step. If you have a scenario where it makes sense to disable this advanced functionality, you now have the ability to do so.

In Class Notebooks (OneNote) educators now have access to the Math “On/Off” switch giving them the ability to enable or disable this feature. This is supported in OneNote for Windows 10 and OneNote Online.
