Click/Tap on the circle (on the bottom right corner) to use it like a counter. Once you click on it, or press the space button, a number will appear of the increment by 1. You can change the increment for the circle by looking what's inside the project. If you click/tap on the Add Number button, it tells you what positive number or decimal number you want to add for the current number in the number generator. If you see the text that says 1e+21 in the orange box in the units scroller, you will get a number with an e notation output. Inside this project, you can even drag numbers around or using the units scroller! Feel free to remix if you want.
