Don’t know about university math, but this applied to a lot of the stuff in my last years of school. Since we always had a part where you were required to solve everything without a calculator you had to be able to do everything without it. For algebra and Calculus it just meant that you were able to do the math more efficiently. For statistics the calculator was basically useless, since it didnt help you if you didnt knew what you had to do, what was basically the only hard part of it.
