Customer Evaluations
Actually, at first I was a hesitate to invest in the ti-81. Lastly, I had made the choice to buy it. I uncover that it's worth every penny. I enjoy it. Trust me, this calculator can do almost almost everything like the ti-83, except that it does not have as a lot memory as the ti-83 and the capability to transfer information. Having said that, I locate that the ti-81 is just about every straightforward to use. Not poor at all
I necessary a excellent graphing calculator fast, and this a single honestly does the job. It is just as wonderful as the later models, don't waste your dollars on the alot more high priced ones. The batteries do go fairly quick although. I have to consistently adjust the contrast due to low battery power.
