5.0 out of 5 stars Casio classwiz fx-991CW in University Life

2025-12-21    -Amazon Customer

A semester in the calculator works well, buttons are tactile and responsive. The main quality of life improvements u notice is the surd function and fractional answers, the fact u can modify the display to suit ur eyes, accuracy is a plus and its durability. The calculator interface is refreshing, readability is eased . Its great value given the graphing function although accessed through ur phone on a website with the QR. The school use is exceptional, and relevant to my Pre Engineering classes and would be using it for my further degree. However in exam time they did call my casio calculator a semi-programmable, had to pull out my sharp and dust off the codes and functions I memorized. The examiners allowed the older model casio class Wiz which is more button oriented than this one which is screen oriented. 🤔 given a university scenario I did have my doubts on that exam certified. If anything I'll invest in the older model casio class wiz. As well

A Perfect Calculator

2026-01-06    -Danny H

I got this for my son in Grade 10. It has 500+ functions in total. Clearly he's not going to need all of them.But, it 10 minutes, with the help of the 150 page PDF, it was easy enough to figure out how to do some of the basic algebra and trigonometry functions that he needs.The screen is a nice size. It shows equations, fractions, and decimals. It's clear and easy to read.You can have spreadsheets and data tables. We didn't get the calculator for all those features, but they're available.It comes with a protective case that covers the screen and buttons. The cover, when removed, clips on the back so it's easy to store.
