Operation

The logic employed by iMalc is algebraic rather than Reverse Polish Notation (RPN). This means that to do a calculation such as 15+2=17, you enter it as seen, or as you would when writing an algebraic equation. You would enter 15, followed by +, followed by 2 and then the equals.

To get 18x3=54 you would therefore: Press 1

Press 8

Press x

Press 3

Press =

and the result, 54, will be displayed.

If you are employing the +/- sign change key, then use it before the equals key eg for 100 x (-2)=-200 you would:

Enter 100 Press x Press 2 Press +/- Press =
