Hey supremum, thanks for your input. I find it odd that the professor said that. I'm going to visit RPI this weekend and I'll ask the same question and if they say RPI isn't the best at pure math, then I probably wouldn't go there.

Re: Algebra Manipulator Program

Thanks for the reply!
Yeah, dragging functions over an equation would be nice. I'll definitely look into that.
There could be a list of function (sin, cos, tan, integral, derivative, floor, ceiling, etc) that I could drag onto the equation.
Very interesting.

Algebra Manipulator Program

hey, I'm making an algebra manipulator program in java. Basically, you can drag variables or numbers around in an equation (like you do in your head) and try to solve problems. so If I have: 2x + 4 = 5y I can solve for x using my program by dragging the 4 over, 2x = 5y - 4 and then dragging the 2 ov...

So this recursive formula came from doing a hyperoperation from the left side to right. like a(4)3 = a(3)a(3)a(3)a the normal approach is { a(3) { a(3) { a(3)a } } } (which is the right to left computation) I'm using the left to right computation and to find b_(n-1) i have to find b_(n-2) etc.. a(n)...
