I used RStudio to work through problem sets, textbooks, and ideas constantly during my time as an applied math student. My concentration was stats, but still found RStudio invaluable for pretty much every math class I took. I say RStudio specifically because it offered the complete package for what I needed at the time. Built-in graph viewing, workspace management, etc. As another commenter said, pretty much the best graphing/scientific calculator I could ask for.
