R is my go-to for this, and one I recommend often. It makes a nice calculator language (with only a little weird syntax), has a very rich standard library of functions, and is reasonably fast. The great thing about R is that it scales well with task difficulty. It works well for a couple numbers. Then you can use data frames, and the Tidyverse (https://www.tidyverse.org/ https://www.tidyverse.org/) packages to do a lot of data analysis (especially dplyr, which is extremely powerful). Finally, if you want to look at your data, the built-in plotting capabilities are solid, and ggplot2 is both extremely powerful and reasonably easy to use.
