The Calculate Functions menu is similar in appearance to the Calculate menu. It has a keypad you can use to construct an expression in the currently active argument box. For example, you can select the square-root function and specify the argument as A+B, which inserts SQRT(A+B) in the Calculate menu.
Another way of specifying the argument is to use the mouse to select part of the expression being formed in the Calculate menu then click Functions to copy the selected text to the argument field in the Calculate Functions menu.
