This was the first calculator I owned, we had to buy one when I was in grade 10. My older brother and sisters used a slide rule. This was $50 and I got a deal because the school ordered a lot at a time. It was called a scientific calculator but really only did a few functions like sine and cosine. It had a red display and took a 9 volt battery. Times have changed!
