Scientific Calculator fx-991

This has been very helpful for my Electro Technology classes. I don’t own a physical one and this is so useful plus free. There are ads but it’s not that bad they are not in your face. For the most part you can ignore them and they don’t throw it in your face forcing you to pay for it.

I have had a great time using this calculator for school and it has helped me in so many ways

I tried several popular calculator apps and they all have terrible user interfaces. I was looking for something as close a scientific calculator as possible, and this one is the best I’ve found. One suggestion would be to change the ☐² to X² and ☐⁻¹ To X ⁻¹
