Synthetic division, anyone?

[Googi]

Huh? It's just a calculator.

Can your calculator factor x^2 + 5x + 6!?

Of course it can by finding the zero values, but can it actually give (x+2)(x+3) at once?

Yea.

[xXziroXx]

So can my calculator, nothing special. I can even make games with mine! (seriously!)

Nah, I still think it's nice though. And it's special on Graal. I never saw one before (on Graal).

Goob job Yen!

[Omini]

Kinda makes me wish I could script... well I can but only a little in GS1, when it comes to GS2 I havn't got a chance.

[excaliber7388]

nice

[Python523]

Just what I always wanted, a factor tool that can't handle fraction factors

Great! I'll be sure to sign on Graal to use a calculator when my TI runs out of battery. I hope you update this calculator to perform multivariable calculus functions.

Yes.

[Yen]

My calculator can't.
I feel gimp..

Go spend $200 on a TI calculator

[Yen]

I have one.

It can't do factors as far as I know, though.

[jake13jake]

Ugh I hate stacks.

[Prozac]

... so am I the only one who loves programming
but hates math?

nope, i despised all my math classes.

[jake13jake]

Yen, you should just make a stack loader that will take in for a string of numbers and operators... and perhaps make some sort of interpretation for variable names.

[Prozac]

since there is talk of a data structure (a stack)
let's see a gscript bubble sort
or better yet
a red-black threaded binary search tree
(the data structure used on most operating systems to store and access information on hard drives)
