Response regarding the Casio FX-260 Solar:

There is a difference between functions and formulas. But I just got
word that the calculator can have only 4 functions so this Casio will
not work. I found one on the Internet: Brother 418E 4-function
calculator - any 4-function only calculator will work. And the four
functions are add, subtract, divide, and multiply. I'm sure you can find
others on the Internet as well.
I hope this has helped.

Interestingly, the Brother 418E is an antique, an antique with Pi, square root, and other functions...
