What is the difference between TI 84 and TI 85 calculators?

Question

-what subjects do they each cover
-is it bad to get a TI 85 when you are only in Algebra 2 (could it possibly be to advanced?)
-what do you recommend
-is there a huge difference in pricing?

Answer 1

What's the difference?

TI 85 - TI 84 = TI 1.

No but seriously.

They cover about the same subject matter, for high school. They would be more or less equivalent, in that regard. The 85 can provide higher-level functionality, but at a cost. For one, it's more expensive in general, and it has been superseded by the TI86, which is invariable more expensive than the 85 or 84.

There is no reason to have an 85 for Algebra 2 - get the 84. You may want to, years from now, get a more advanced calculator, but wait and see. At that point, the 85 or 86 will be cheaper, and you may not need it (or may not even be allowed to use it - many college math programs forbid calculators).

The difference in features involve advanced calculus, statistics, and programming functionality. It should not affect your ability to do your algebra work. In fact, if you want to save more money, go with an 83 or 83+ instead, which still gives you graphing capabilities.

As for pricing, basically, a TI 85 will run $50 on ebay, and may be found in retail stores, but mostly retail stores will offer the 86 at $80+ (and the 85 for similar price).

On the other hand, an 84 will cost you $90+ retail but only $50 on ebay and the 83 (my pick if I were you) will run you $20-30 on ebay - much less than $50 or $80.

If anyone is still looking, you definitely want the TI-85. I used mine through college and it was also the first device I ever programmed on. You can buy these for $20 on Ebay, whereas the TI-84 will set you back three times that amount. THe TI-89 is nice, but those are $100. If you can find a cheap TI-85 on Ebay or Amazon for $20, just get it. Do not worry about learning how to use it. They are really self-explanatory, and you can always hit up the google machine on your phone. You can really do a lot with the TI-85. It is great for calculus, but also other subjects.

Answer 5

The TI-84 has a 96x64 screen. The TI-85 and TI-86 have 128x64 screens. TI-83 and below are usually used in high school. 84 and above are great for college.

I have always used the TI-85. I really liked it, and it got me through every math, statistic and finance class that I had in college. I was a business major.

I don't think the TI-85 is still manufactured. There is a TI-86 and TI-89. You may be able to find one used.

The price for the TI-84 and TI-86 are fairly close - $75 - $90.

I would look at the higher model, due to having a little more functions. You can use if you go to college also.

Good luck.

Answer 6

there isn't a whole lot of difference between the two. The 85 is a tad more advanced. One thing the 85 has that I like is conversions for example, it'll convert ft/sec to miles/hr and so forth. The 84 has a lot of preloaded apps and crap you'll probably never use. It's also layed out a little nicer than the 85. However I recommend getting whatever the teacher uses. I also recommend buying yours off eBay. There are a lot of HS/College grads who don't need them anymore and sell them for like 40 and 50 bucks.

Answer 7

I use a TI 30 for Algebra 2, and it's plenty. I think a TI 85 may be too advanced, and its really, really expensive. If I were you, I'd stick with a lower number of calculator. Hopes this helps.

The TI-84 Plus and the TI-85 are fairly different models, despite being quite "similar" in naming. Here are some basic differences: TI-85: - Released in 1993, replaced by TI-86 in 1997, both now discontinued - Zilog Z80 Processor, clocked at 6 MHz - 28 KB of RAM available, out of a total of 32 KB - 128 KB of ROM - Has a 128×84 pixel screen TI-84 Plus: - Released in 2004, successor to TI-83 Plus, both now the most popular graphing calculators for high schools - Z80 Processor, clocked at 15 MHz w/6 MHz compatibility - Silver Edition also released in 2004, successor to TI-83 Plus Silver Edition - 24 KB of RAM accessible, out of a total of 128 KB (though newer models have 48 KB accessible) - 480 KB of Flash ROM accessible out of 1 MB (on regular edition); 1.5 MB of Flash ROM accessible out of 2 MB (on Silver Edition) - Has a 96×64 pixel screen The interface is also fairly different between the two calculators. The TI-85, I believe, has a more visible menu-like input system for commands, whereas the TI-84 Plus relies more on menus within buttons. The functions themselves are also quite different, so if your daughter's teacher explains, for example, how to find the linear regression based on data points (On the TI-84 Plus: [Stat] > Calc > 4:LinReg(ax + b)), your daughter would have to figure out a different way to do it (On the TI-85: [Stat] > [F1](Calc) > xStat > yStat > [F2](LinR)).

Answer 9

You know I think a TI 83 is plenty of calculator for high school.

Answer 10

If your algebra class teaches keystrokes on the 84, you should get that one. There are different keystrokes for the same functions and most teachers are irritated to have to spend time teaching both ways..If not specified, they are both graphing calculators and either will fill your needs.
