Green flag to start and reset. Thanks to @DragonBot1000 for inspiration and @StratfordJames or @TheCactusMaster for numbers that show up on the calculator and coding for that Hit the green flag, select numbers, etc, and then hit 'space'. It will calculate! Make sure to hit space after hitting keys. If you hit the Giga button, it does different things based on what point you are at in the project.
