Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How to calculate an expression that is stored in a string in C++
This parser looks like it might be appropriate. This one looks like it's based on the same code, but looks potentially abandoned.

If you have 4+3*2, is there an algorithm to calculate this in one pass? Or do you need to convert to RPN/postfix, then use another algorithm to calculate?
It can be done in one pass. I implemented a pratt parser for this kind of expressions: https://github.com/foolnotion/pratt-parser-calculator
What are some alternatives?
