The project consists on proofread a math research paper. You don't need to understand the math, not the content of what is being said. You just need to look for misspellings and grammatical mistakes. However, you do need to be used to reading mathematics, as we have a particular way of using symbols within sentences and a particular way of saying things that if, you've never read math before, might sound too foreign. It shouldn't take more than two or three hours. If you see an obvious way to improve the sound of a sentence, that's welcomed too, but I don't want you to spend too much time on that.
