Question

Is it possible that, on a fx-115Es PLUS that you can insert a matrix bigger than a 3x3?

Answer 1

No.

Answer 2

Great -_-, do you know a calculator that does?

Answer 3

TI-Nspire.

Answer 4

I can't say if others do, but that's the calculator I use.

Answer 5

Oh, isn;t that the one that can do polynomial multiplication like if you do x^2 times x it gives x^3, ik that's basic but Im trying to do sequences and I have to set up multiple equations and solve for a b c and d and I can't do rref mode by hand :O

Answer 6

Yeah, that's if you get the CAS version. The non-CAS can solve equations too.
On my CAS. I can solve as many as I want. Far more than 4 variables.

Answer 7

and what about TI-89 Titanium?

Answer 8

and why dont you acccept messageS?

Answer 9

TI-89 Titanium seems good (and should be able to do such calculations) from what I heard; but it's nothing like the NSpire.

Answer 10

Ok, now I read you can't use this on the ACT but you can use it on every else like a SAT/AP, so what do you recommened in its place?

Answer 11

ACT will never have you solve more than 2 equations if any.
You can get the TI Npsire; just not the CAS edition for the ACT. It's on their website.

Answer 12

OK can you tell me the different versions they have so i dont get confused, I know theres a CAS/ non CAS, a teachers edition but i think i saw another one it said CX, idk are there anymore and if so what is the difference witht them?

Answer 13

CX is the color screen version.
CAS means it can do stuff like x+x = 2x.
TI NSpire is just a normal calculator that can do lots of advanced stuff. No color, no "x+x = 2x"
TI NSpire CAS is just like the above, but has the algebra function.
TI NSpire CX is just a TI NSpire with color screen and a few extra features.
TI NSpire CX CAS is the TI NSpire CAS with color screen. This is the most advanced.

TI NSpire CX CAS > TI NSpire CAS > TI NSpire CX >TI NSpire

Answer 14

thats cool so which one do you have?

Answer 15

TI NSpire CX CAS

Answer 16

Of course, what wqas the cheapest price for that?

Answer 17

$120-$160 New.
Get it from ebay for a good deal. The price will hardly drop.
I bought mine $140 in 2011.
