Qual fonte padrão o MS Word 2013 usa para compor fórmulas?
Ele usa Cambria Math .
Out of the box, Office 2010 and 2013 have only Cambria with all of the math characters that are needed for the Equation Editor.
You can verify this by clicking "expand link" at the bottom right of the "Tools"box in "Equation Editor" > "Design" tab:
After some considerable effort, I have still not found a compatible font so I have posted this with Microsoft Partner Support and after some back and forth, this is what they said:
"Cambria Math is the only supported font that can be used in Equation Editor in Word 2013 for the time being. Anyway, the DEFAULT FONT is a drop down box and it will have alternates after some improvements are made by the developing team."
