Quality calculator, great for engineering.
Good quality, a little confusing but once you know what you’re doing it works wonders for all sorts of math.

Casio scientific calculator
These are the best calculators I’ve used and they are a great price, I’d recommend getting them. The box comes with the calculator, the manual, and all the other information you need. The screen is bright and easily readable, it responds quickly to pressing the buttons. The quality is great, the plastic is smooth, high quality, and a nice dark grey colour. I got these for my schoolwork and they cover everything I needed. I definitely enjoyed this purchase, and recommend anyone who needs calculators to buy these.

Great calculator but one only con
Overall it’s a good calculator and performs all the necessary functions that you’ll need, especially for disciplines like engineering. The one problem I have with it is when storing functions, an extra step of multiplying the answer by 1 must be completed before storing the function. This is to prevent the calculator from performing the operation again and storing that answer.

Good calculator
This calculator is of good quality and helped me survive through high school Physics and Advanced Functions. (Don't use this calculator for 12 U trig. It doesn't give answers in pi). Otherwise, it is great!
