The first text area to appear contains the number to be converted to binary form.
The "Workings only" table is intended for any rough workings and calculations you may need. This table will not be used
during checking of answers. Look on it as on screen scratch paper.
Put your solution to the problem in the second table, labelled as "Enter here".
Enter a '0' or a '1' in every cell to create the solution.

If any cells are left blank, a warning message will appear. Please complete all empty cells.
Ensure that before pressing submit, no cells in this table are highlighted / selected. The program will not recognise
input as complete until the focus has moved away from the cell. If a cell is still selected, a warning message will appear.
