High School What Programming Language Can Handle 30-Digit Integers and Matrices for Free?
I've been looking for a free download of a programming language that is easy to use and handles large numbers for a number theory problem I'm working on. I will report my results here after I use it. My TI isn't powerful enough and my other programmable calculator that I downloaded, graphcalc...- approx

Undergrad Integer roots in quadratics with fixed b and exponential c
So, lately I haven't been able to give it a lot of thought, but recently I realized that there are large lists of pythagorean triples which might help find my "c" since p^2+4c must be a perfect square in order for the quadratic formula to work out right, and since pythagorean triples are of the...- approx

Undergrad Integer roots in quadratics with fixed b and exponential c
thanks for the ideas, Obydefinition. I will have to think a bit about them. Actually, the reason I came up with my quadratic form is because it can be proven that forming a quadratic x^2 + bx - c, where c is as described before (highest prime factor of c is greatest prime p less than square...- approx

Undergrad Integer roots in quadratics with fixed b and exponential c
put another way, your quote (below) is completely right, except use x^2 + px - c = 0. Thanks again.- approx

Undergrad Integer roots in quadratics with fixed b and exponential c
I truly apologize for not having this conjecture organized when I wrote it - it was an old idea for me, but put into a new form and I hadn't ironed out everything I needed to have to make it clear when I first wrote it. Here is how it should go, only slightly different than it started out...- approx

Undergrad Integer roots in quadratics with fixed b and exponential c
very good point: I have noticed that the conjecture only "kicks-in" for p>9, when p<9 we sometimes need x^2 + px + c = 0 in that case x^2 + 5x + 4 = 0 has the roots 1 and 4. I know this seems kind of arbitrary, and it is. The original version of my conjecture said "plus or minus c" but I...- approx

Undergrad Integer roots in quadratics with fixed b and exponential c
Thank you, Hurkyl, for your assistance in this matter and for the links to smooth numbers and primorials. Though I haven't looked into your computations in detail, they seem sound. I do appreciate you having an open mind at the end: You seem to recognize that that each event of finding...- approx

Undergrad Integer roots in quadratics with fixed b and exponential c
Last attempt at asking for help! Hello, I'm really surprised that nobody has come up with any advice on how to prove such a beast. I've been working on it, in a slightly different form, for about 13 years and I thought for certain that when I came up with a quadratic formulation of my...- approx

High School What exactly do the signs <=> and => mean?
Basically, A=>B means if we know that A is true then B is true, also if we know that B is false we can show that A is false. If all we know is that A is false we aren't certain about B, and if all we know is that B is true we aren't certain about A. A <=> B means they are either both true or...- approx

Graduate As for the original question: Is nullity a valid concept in mathematics?
interesting... Well, I have always felt uneasy with saying "you just can't divide zero by zero, it doesn't mean anything" or whatever. I think what is interesting here is, if I understand you correctly, you are making a distinction between simply dividing by the number zero, and dividing by a...- approx

Program Hey, sorry if I sounded abrupt or harsh, shouldn't be typing if I don't have much time to think-over what I'm saying. Would anybody out there know how to use the program Maxima? I recently downloaded it but I haven't had time to learn the lingo. It uses much bigger numbers than my...- approx
