Press green flag once to start. Drag a number to one of the addend variables, that variable will then hold that number. Then, drag another number to the other addend variable. Click on the lever to generate another batch of numbers. Once you are happy with your numbers, press on the equals button to generate your answer. You can also put your own factor by clicking on the custom factor button in the bottom left. Note: I have only added numbers up to 300.
