I'm using Excel 2002 with Windows XP. How can I write an equation in mathematical format.

For example:

b + (c)^n

a = --------

d

The equation doesn't look right but it is "a" equal to "b" plus "c" to the power of "n", all divided by "d".

Is there a mathematical font in Excel that makes this type of presentation and calculation possible?

Your help is appreciated.

Thank you
