David S says:

I have the fx-115ES Plus and I’m getting a fx-9860GII for Christmas. I’m a big fan of all calculators. I really like Casio and TI. The joy of understanding math and it’s practical applications is an awesome gift. My college makes sure we understanding how to solve math questions without the calculator. It makes one appreciate the use of a calculator so much more. Thank you for making these videos.

I think I still like the Casio 115es plus better. I didn’t see any functions on this one that the 115 does not have and the function layout is more intuitive.
