This program looks like simple desktop calculator, ya you can't use mouse, though numeric keypads will work well to do calculations. See how is this calculator functions. I have made the coding as simple as possible so that you can follow the code and understand it easily.
If you want do more scientific calculations, you may try yourself at home. It will be fun to do programming, believe me.
Enjoy your programming.

    CLS
    FOR P = 20 TO 1 STEP -1
    IF P MOD 2=1 THEN
    PRINT P
    END IF
    NEXT P
    END
