Have you had a problem trying to get any other operation but Addition to show up on the bingo sheets?

Try this:

By default, only Addition answers and questions appear on the bingo card and call sheets. To select an operation, click on the operation symbol.

When the selected operation tab appears, check the Include operation checkbox (i.e Include Subtraction).

To remove an operation, uncheck the checkbox.

Once you have made all of your selections, make sure to click the Generate button on the toolbar to refresh the bingo cards and call sheets.
