In a balance sheet, Does the Treasury Stock have to be subtracted from retained earnings?

Why is it so, because I am facing a problem and I don't really understand it in my financial accounting class?

Yes,
Treasury stock is usually a repurchase of co. stock. Because a co. asset-cash- is used, the result is a reduction of shareholder equity.
