Slight tangent - but back in the day while I was attending university I started turning in all my engineering assignments using MathCAD. MathCAD occupied this weird space of a living document for math with additional Mathematica like functionality for symbolic manipulation. I certainly don't feel to this day like I lost anything vs doing everything tediously by hand 100% of the time. My professors liked it so much they standardized on it and licensed the student edition for the entire department.
