my calculator

Yesterday I lost my calculator.

I had it since freshman year of high school. It has been through a lot with me. Every Algebra, Geometry, Precalc, Calc, Statistic, Econ, and every Accounting Test..
I called where it was last seen but no such luck. I really hope that whoever took will get as much use out of it as I did.
Here is my calculator's sister that I had to buy at Walmart.

Hopefully it will give me as much luck as my old one did.
