Am trying to construct an equation in PowerPoint 2010 with the Equation Tools. I want to change the size of a couple of individual characters. (Specifically: I want some enclosing braces to be much larger than they are.) I can't believe there's no way to do this, but I can't find instructions anywhere. Anyone have any ideas? Just to be clear, I am not trying to change the font size of an entire equation, just of a couple of characters. Thanks.
