Question about TI Calculators

In summary: Maybe it's because it's a classic and collectors are willing to pay more for it. In summary, the TI-89 is more expensive than the TI-89 Titanium on Amazon because it has more advanced features such as a computer algebra system. Both models have differences in memory size, but the TI-89 Titanium is considered to be better. It is unclear why the older version is more expensive, but it is recommended to take advantage of sales on Amazon to get a better product for a cheaper price.

Amazon often has sales and sometimes you can get a better product for cheaper.

Corporations do do this, you know. For example, at McDonald's I can get a 99cent extra large soda for cheaper than I can get a medium, 1.29, I believe.

Looks like a good time to buy a ti-89, and yes it's better than both those other two calculators. It's been a good one in my experience, however, I want to get a RPN program for it.

The TI-89 has what is called a computer algebra system or CAS, which can locate symbolic solutions to problems, like finding derivatives, integrals, and whether or not infinite series converge.

The TI-83 can only find numerical solutions to problems, like the roots of polynomials and the coefficients of systems of linear equations.

And I have no idea why the older version of the TI-89 is more expensive.
