TI-89

Just like a six-shooter was a cowboy’s tool of choice in the Wild West, my TI-89 is my ally at work. I’ve found it is very versatile and helps me solve problems and equations quickly. There is a story and lesson behind it.

I got a bonus from work about 3 years ago. Most people would have probably spent the money on other things, but I bought tools that would help me in the job. This calculator was one of them. One thing I learned after this was that successful people invest in themselves, be it tools, education, or other things.

I know some that like RPN would like the HP-48G, but have you ever tried to buy that at a local store? It is so hard to find those things, and after all, everyone else uses the TI series of calculators. If and when I take more calculus courses, the TI-89 will work nicely for them.
