Are you doing this with paper?
If not then I recommend looking into software that will let you develop flow charts....like Visio, or something free like OpenOffice Flowchart.

abigail,

Do you have a basic speficication for what you want to do?

Once you have the specification, you can start thinking about I/O flow, and how you'll deal with each piece.

But ..... the bottom line is that you need your requirements/specification to start with.

Cheers!

Presumably your calculator will perform operations like:
((4.7 - 3.1)/16.2)+7.8.
The flow chart would describe the following with symbols:
"add 4.7 to 3.1 then divide by 16.2. Add 7.8 to this result". If you can represent the above with symbols now generalize the expression and draw your final chart.
