School batch program.(math)

[cdh473]

Ok. So i have a created a program called SolutionFinder, and I would like for you guys to tell me if it's any good.
My teacher saw me programming in class one day and said "Hey, I need a programmer for something." We talked about it then she said she needed a program that actually figures out the solution to an equation, for example,
10x+10=10+10. So it would need to find X, and x would = 1. But she wanted it to show the work. So then I had to make it do this instead:   10x+10=10+10
                                        10x+10=20
                                               -10 -10
                                               10x=10
                                               /10  /10
                                                  X=1
Now, I decided to do this because it would make me do my homework a WHOLE lot faster, considering the fact the we would only get half credit for not showing work. Here is the program: [Download Link Removed]

If it's a Batch program, can't you post the code?

I removed the link because:
1. It was a rapidshare link
2. It was an .exe file
3. You're new here

What's so bad about rapidshare?

[BC_Programmer]

Aside from the fact that it blows?

[Carbon Dudeoxide]

Another list:

1. We have an uploading system
2. There are other uploading websites
3. Perfect place for a virus

[cdh473]

So how am i supposed to get a link on here? I mean, I converted it to .exe so you wouldn't see the source code, but uhh... is there any site u guys will let me link it to?

[Carbon Dudeoxide]

So we can't see the source code? ROFL

I'm afraid you will have to post the source code or don't post it at all.

[Helpmeh]

Another list:

1. We have an uploading system                   (Size and extension restrictions)
2. There are other uploading websites          (how does that make rapidshare bad)
3. Perfect place for a virus                              (same with all the others...)

Okay, try Cdh473's program. Get infected. See what I care.

Was I protecting the OP's program? No
Was I protecting rapidshare? Yes

[Carbon Dudeoxide]

*sigh*

Ok, what do you like about rapidshare?

[Helpmeh]

*sigh*

Ok, what do you like about rapidshare?

What do you not like about rapidshare. I don't use it much, but I was just wondering what you have against it...other than these...

1. We have an uploading system                   (Size and extension restrictions)
2. There are other uploading websites          (how does that make rapidshare bad)
3. Perfect place for a virus                              (same with all the others...)

[Carbon Dudeoxide]

Well for one, the darned time limit thing.

Anyways, that is besides the point. This topic is not about Rapidshare, but Cdh473

[Helpmeh]

Well for one, the darned time limit thing.

That I must agree with...anyway...I think I could check it with VirusTotal...but I'd have to download it first.

[BC_Programmer]

I on the other hand am not wasting my time downloading an EXE and grabbing the batch code in 5 minutes when it could simply be given here.

[macdad-]

We dont even know if its supposed to do what you say its supposed to do, since for one thing it could be a virus(not that we don't trust you its that your kinda stalling about the source code which seems suspicious)

[Xenfire]

Agreed.
We can't help you here unless you post the source code.
How else are we supposed to help you our if we can't see if you have any problems?
Plus you only have 2 posts, so you aren't trusted much.

[Helpmeh]

I trust this person less than anyone on /b/.

[Xenfire]

i trust /b/ with my life
Like that time they told me to delete system32

I was told that I should type FORMAT C: on the command prompt once...

The original poet was about  solving a math problem using a computer.

This sort of thing is sometimes called Algebra Solution Software.
Did the professor want him to write the program or to find one already written? There are lots ready to use programs. Some with tutorial ans graphics to help teach. Some free. Many not.

Google Algebra Solution

[cdh473]

well... i have absolutely NO IDEA how to make one autorun so...yeah..... i couldn't do that even if i wanted to.

[Carbon Dudeoxide]

We didn't say anything about an autorun......

[Geek-9pm]

Solving an algebra problem is often in two areas:
1. Some variation of one or more a linear equations.
2. Solving a quadratic equation, which boils down to factoring.

The linear equations are rather straight forward.
The other kind is piratically guessing at the answer.

The are computer programs that do both.
Some are free. Many are sold or rented as "Homework Cheats".
look at this:

Some of the great mathematicians felt that building a machine to solve huge t problems was a worthy goal of their study. Does your professor agree with that?

[BC_Programmer]

for some reason I'm suddenly reminded of the quadratic formula,

ax^2 + bx + c = 0

which can be factored with:

(-B+-SQR(B^2-4*A*C)/(2*A)

which can return both X intercepts of a parabola if they exist.

[Geek-9pm]

for some reason I'm suddenly reminded of the quadratic formula..

It's all coming back to be now...

[macdad-]

He may be saying a completely different problem he wants to solve that may be irrelevant to Algebra.

[Geek-9pm]

We talked about it then she said she needed a program that actually figures out the solution to an equation, for example,
10x+10=10+10.

This is what he first posted. It was to solve an equation where some values are know, but one item remains unknown.
x= (10+10) /(10+10)      is a match problem. Only one X by itself.
10x+10=10+10               is an algebra problem. X is not by itself.
x = (10+10)/10x+10)      is an algebra problem. More than one X

Well... Never did get straight As in that class.
(Actually, I flunked the first  year.)

What happened to cdh473? Looks like he doesn't need our help anymore....hmm...

[Helpmeh]

What happened to cdh473? Looks like he doesn't need our help anymore....hmm...

That's because he knows that we know that he knows... in the end: He knows we know.

[Xenfire]

because that makes sense..

[Helpmeh]

because that makes sense..

But you see, if he knows we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know that he knows that we know...


Anyway, it is a failed attempt at putting a virus on our systems...

***code not showable***

Somethings up....

[cdh473]

how.....

That just had something
you didnt need to see
that part of the code wasn't needed
...*censored* could be up close

[Helpmeh]

We didn't need to see? If you post the source, you post the WHOLE thing. And why do we not need to see it?


Anyway, WolframAlpha can do this online, no need to download anything.

[BC_Programmer]

It's probably just a password. not really needed for debugging.

[Helpmeh]

It's probably just a password. not really needed for debugging.

why would he want to password protect it, then post it here?

[BC_Programmer]

..

he DIDN'T post it. that's the part he's not showing.

On the other hand, it wouldn't make sense as a password since there was no user input, and it's looking at %action%. so what you posted before stands true.

Additionally, I cannot see why it wouldn't be showable; It's just a batch file.
