Using Parentheses

See also Entering Formulas.

Parentheses are used to repeat parts of a compound. For example, C6(COOH)6 has 12 carbon atoms, 12 oxygen atoms, and 6 hydrogen atoms while CH(C(CH3)3)3 is a carbon atom with three C(CH3)3 groups attached and a hydrogen atom attached.

The program supports any number of layers of embedded parentheses. Furthermore, curly brackets, { and }, are treated as parentheses, while regular brackets, [ and ], can be treated as parentheses if desired (see the Program Preferences Window).
