I bought a Casio fx-991es Plus back in high school, when I was taking Math 31. I bought this model because I read it was virtually identical to the Faculty of Engineering approved Casio fx-115es plus. Apparently the model number is different, but the calculator is identical?
Difference between Casio fx-991es plus and fx-115es plus?
Now that I'm taking STAT 151, looks like I need to get an approved non-programmable calculator for the exams, and get a gold sticker on it. Does anyone know if my Casio FX-991ES Plus calculator would still be approved? I'd honestly prefer not to spend another $24 for a new calculator.

Casio V.P.A.M. calculators are scientific calculators made by Casio which use Casio's Visually Perfect Algebraic Method (V.P.A.M.), Natural Display or Natural V.P.A.M. input methods.
V.P.A.M. is an infix system for entering mathematical expressions, used by Casio in most of its current scientific calculators. In the infix notation the precedence of mathematical operators is taken into account. According to Casio, in V.P.A.M. calculations can be input exactly as they are normally written. Functions, operators and symbols are shown on the calculator display and calculations are performed according to operator precedence.

- 2.2S-V.P.A.M. (Two-line, Multi-replay)
History[edit]
The V.P.A.M. name was first introduced in 1994 with the introduction of the fx-991S scientific calculator in Japan. In 1998, the Casio fx-991W model used a two-tier (multi-line) display and the system was termed as S-V.P.A.M. (Super V.P.A.M.). The model featured a 5x6-dot LCD matrix cells on the top line of the screen and a 7-segment LCD on the bottom line of the screen that had been used in Casio fx-4500P programmable calculators.[1] The S-V.P.A.M. system was also used in the other W series models and also the MS series of calculators that followed. V.P.A.M. is similar to the Direct Algebraic Logic (D.A.L.) used by Sharp in some of their scientific calculators.
The fx-82ES introduced by Casio in 2004 was the first calculator to incorporate the Natural Textbook Display (or Natural Display) system. It allowed the display of expressions of fractions, exponents, logarithms, powers and square roots etc. as they are written in a standard textbook. Natural Display uses natural representation of mathematical expressions and formulas through a 96 × 31 dot matrixLCD display. Casio uses the term Natural V.P.A.M. for the fx-ES Plus series of calculators which are the upgraded version of the fx-ES series.
In early 2015, Casio introduced a new line of calculators called CLASSWIZ for different markets, featuring a high resolution (192 × 63) dot matrix Natural Textbook Display and incorporating spreadsheet functions in some models. This series of calculators is called the fx-EX series and it succeeds the fx-ES Plus series of calculators.

Comment
I love the simplicity of the Casio fx-991EX (ClassWiz). The use of a natural textbook display and high resolution screen allows me to present mathematics the way students see mathematics in their textbooks. The ClassWiz also allows me to teach concepts I never could before. Statistics, data analysis, probability and spreadsheets are all now within the realm of possibility. My favorite feature is the QR Code generator. I now have the power of a graphing calculator in the hands of every student. The ClassWiz allows me to focus on the learning and not the button pushing.
