Brillant, and free, with lots of preprogrammed options. What would be beneficial would be the option to add fixed calculations of our own that could be recalled from memory by name. Remembering the figures, sequence, and brackets for a particular method can be problematic. Otherwise, not a lot of room for improvement.
