### 5/5 — Terrific calculator

*2020-12-04*

I don’t use any of the scientific or trigonometry available but the memory slots and the ability to go back and see previous functions is the big seller.

### 5/5 — Dated but still Great!

*2019-07-23*

Although this Calculator is dated(takes a few seconds to load) it has 4 addition, easy to use, memory slots. It also shows your last 20 calculations on another screen. If you make an error on a long entry you can back out of it number by number!
