Medlin programs have a built in, four function, pop-up calculator that works like a standard pocket calculator (if there is such a thing).
•Press the <F10> key to display the calculator.
•Enter a number and use the <+> and <-> keys to add and subtract.
•To multiply or divide, use the <*> or </> keys and then the <Enter> or <=>.
•To paste the result, click the 'Paste' button, or press the <=> key twice.
•The calculator's tape can be printed by clicking the 'Print' button.
