In summary, three other nice fonts that work with Microsoft Office’s new Equation Editor (these are compatible with Office 2007 or later):
- XITS Math is somewhat compatible with Times (download here).
- Asana Math is compatible with Palatino (download here) and if you don’t have Palatino, you can download it here, among other places
- Latin Modern is the LaTeX font of choice. There is a math font (download here) and a whole family of text fonts (download here). Note: these may not look good on screen, but they look just perfect when printed.
