Hello. I am using TexMaker and want to write a formula in my document. I need to use the amsmath package since I want to number the equation. I have attached my formula.

As $\displaystyle\color{blue}{\textbf{MarkFL}}$ suggested, I posted this formula in another website and found the solution there. Thank you $\displaystyle\color{blue}{\textbf{MarkFL}}$.

Glad you enjoyed my disclaimer, Sir phrack999. 50% fact, 49% joke and 1% still to be determined. Wait till you see Sir Denis' disclaimer involving his coffee soaked ramblings. Supposed to be "sobered state" on his part but is anyone really sober under coffee? Pure water intake perhaps but coffee? Ah yes well enough about beerlosophy.

Is it necessary to have somewhat eccentric spacing, such as $\displaystyle \frac{\ \ {\text{s}}\ \ }{\ \ {\text{b}}\ \ }$ rather than $\displaystyle \frac{{\text{s}}}{{\text{b}}}$?

I have considered it but the possibility that readers might overlook a disclaimer (and think that my posts are reliable and serious) if it were placed in the signature section (a habit I'm guilty of) occurred to me. I have therefore no choice but to forewarn would be readers by copying and pasting my disclaimer before they decide to invest in my statements. Kinda like how investors read into opinions of CPAs first concerning an organization's financial statements before they make any informed decision, to invest or not, in an organization (profit or nonprofit).
