Texas Instruments TI-83-PREMIUM-CE user manual

I'm sorry but it's a misunderstanding. The TI-83 Premium CE is a physical calculator product manufactured by Texas Instruments and it is not free. You have to purchase this product from a store or online retailer. There's no such thing as "downloading" the calculator because it's not a software.
You can find calculator simulators for your PC or smartphone, but keep in mind that these are often not free and may not fully replicate all the functionality of the TI-83 Premium CE calculator. If you're after the software that is typically used with the calculator (for example for programming or uploading data), it's TI Connect™ CE Software and it can be downloaded free from the Texas Instruments website.

Yes, TI-83 calculators are still used, although they have been largely replaced by newer models such as the TI-84 Plus and TI-Nspire calculators. Nonetheless, the TI-83 is still commonly found in classrooms and used by students for basic math calculations, graphing, and statistical analysis.

There are a few reasons why TI-83 calculators are still expensive:
1. Brand reputation: Texas Instruments (TI) has established itself as a reputable brand in the calculator market. The TI-83 is one of their most popular and widely used calculators, which has led to its continued demand and higher price tag.
2. Limited competition: Texas Instruments dominates the graphing calculator market with its wide range of models. Although there are alternatives from other brands, TI calculators are often favored by schools and educational institutions. The lack of significant competition allows Texas Instruments to maintain higher prices.
3. Niche market: Graphing calculators like the TI-83 are primarily targeted towards students, particularly those in high school and college-level math and science courses. Since these calculators are often required or recommended by educational institutions, their demand remains consistent, keeping the prices up.
4. Durability and longevity: TI-83 calculators are known for their durability and longevity. Many users have been able to use the same calculator for several years without any issues, which makes them a long-term investment. This perception of quality and reliability contributes to TI-83 calculators' higher price.
5. Advanced features: Although newer models with more advanced features have been released, the TI-83 still remains a popular choice due to its simplicity and compatibility with standardized tests such as the ACT and SAT. Its widespread usage for standardized testing further justifies the higher price.
Overall, a combination of brand reputation, limited competition, consistent demand from education institutions, durability, and compatibility with standardized tests contributes to the continued high price of TI-83 calculators.
