Tips for using Scientific Calculator

Use a small calculation with a known answer to check how a function behaves before using it in a longer expression. Check brackets, signs and the selected trigonometry settings where shown. Keep the units alongside your working so a correct calculation is not attached to the wrong measurement.

Important limitations

The calculator evaluates the expression you enter; it cannot determine whether that expression is appropriate for your task. Independently check results used for important financial or technical decisions.
