Calculator By Verjul on Nov 20, 2008 - Updated Oct 15, 2011

I forgot when I bought this calculator. Hmmm...maybe when I was still at economic high school. Because at that time I really need calculator for doing homework, etc. After that I continue my study to college at accounting academic field. So...I needed the calculator very much.

That's mean I did have this calculator for around 14 years and still in good condition. I think I drop it couple times but still in good condition. And I never ever change this battery since I bought it until now.

Size 14.5 cm x 7.5 cm x 0.75 cm. Good size to put at your back or at your pocket. There are few function that you can use : sinus, co sinus, trigonometric calculations, alpha, standard deviation, regression, etc.

I am not sure if this product still on market or not at the moment.
