I want to put in a formula which shows an angle multiplied by the square root of a variable. I enter the formula as ±0°0’25" * SQRT{n}. What displays in my document is ±0°0’25 * SQRT{n}. Neither the " nor square root symbol display. If I change the formula to ±0°0’25 * SQRT{n}, the square root symbol displays, but I don’t have the " in the formula.

Neither the ° or ’ cause a problem with the formula, only the ".

How am I do I enter " in an angle without screwing up the formula?

I’m using LibreOffice 4.4.0.3 on Windows 7 64 bit.
