@ A. Gloom
Your use of ..."Pi" button for sum (adding) of a series of numbers & "Σ" button, for product Resonated with me because of my time with APL <https://en.wikipedia.org/wiki/APL_(programming_language)> (A Programming Language), which was in part a logically consistent way of teaching algebra. It introduced the "/" symbol as an operator that applied another operator across all of the element of an argument. For example: " +/ 1 2 " produced 3 as the sum of 1 and 2, while " x/ 1 2 " produced the product of 2. Of course many other binary operators could also be used such a cieiling (for Largest) and Floor (for smallest) APL was very well received and earned a "grace Hopper" award for its implementers, as well as achieving considerable commercial success. The underlying concepts are extremely logical and reduce many of the notation problems that come from trying to standardize the expression of algebraic formulas, functions and operators. Thank you for sharing your work and for your contributions to the group.
