Excerpt: This was the very first scientific calculator I ever owned, many years ago. At the time I had just started high school and had only just been introduced to more complex mathematics where a basic calculator just wouldn't cut it hence why I needed one with more functions. At the time, the calculator was about £10 from any stationary shop. I believe I got mine from WHSmiths but this model is now only available online, usually through re-sellers, as it is a very old model.
Pros: Solar power, good transition from basic to scientific calculators
