Basic help:
Combine values and function calls into expressions with the operators, following the standard rules of arithmetic. The expressions are logged in the ticker on the left side of the screen, with the answer displayed just to the right (or below, in the case of long expressions / answers) of the expression.
On the right side of the screen is the last answer, presented in many separate formats. Click on any answer on the left to re-display all of its formats on the right, click an expression to re-run that expression. Click on any version of the answer on the right, and it will be selected, for easy copy and paste elsewhere. Press ESC any time to re-focus the input box.
