Enter a number when it asks for one (no decimals). It will then tell you whether the number is prime or not. To enter another number, press space. Sometimes the number does not print correctly on the screen so you will need to click the green flag again. A "prime" number is an integer that can only be divided by one and itself without returning a decimal. When we are talking about prime numbers, we are always talking about integers; not decimals, not fractions, not irrational or imaginary numbers.
Thanks to my college CS 142 class for teaching me how to program in C++. This project is an idea that came to my head at about 3 am during finals week, almost in a fever dream. So, of course, I had to make it. Luckily C++ is pretty translatable to Scratch. Without taking that programming class, I would not have had the skill to do this. All coding credit to me. This is quite a simple project, so I doubt that I am the first one to make something like this. However, I used no source other than the knowledge I learned this past semester.
