50th post.

Hmm, my solution:

OPEN the brackets!

So, do:

repeat until (problem) doesn't contain [ ) ]
scan for first instance of [ ) ] in (problem)
find first instance of [ ( ] before first instance of [ ) ] in (problem)
if (symbol before it) = +
delete brackets
if (symbol before) = -
replace all + with -
replace all - with +
remove brackets

etc.

Get it?

Not exactly... hmm
Which member will do this?

Hardmath123 · 2011-03-31 10:29:17

I guess I will...

Basically,

1 + (2 - (3 + 4)) becomes:
1 + (2 - 3 - 4)
1 + 2 - 3 - 4
3 - 3 - 4
0 - 4
-4

The idea is to not solve anything until all brackets are out of the way.

4. How 'bout we call this Xenon?

applejack · 2011-03-31 11:27:42

Few??? I'm active everyday, when you're sleeping. You're active when I'm sleeping, usually. I'm guessing you're on the east coast. they have more educated people there.

Sorry I haven't been active...it's a rather annoying thing called school smile

How do we plan to allow for functions that are not single character, but a short string, a.k.a. sin (x), sqrt(x), etc ?

Also, instead of distributing the operator to the contents of a parenthesis, why don't we just evaluate the contents of the parenthesis, and then use the operator on the result? I feel like distributing the operator is needless hassle. Correct me if I'm wrong, please.

Wouldn't that be harder? Instead make a program that splits it into a list with different characters, and search for "(" and ")". Then make it evaluate the expression between those( tell me if you want me to do it.)

hpotter134 · 2011-03-31 23:19:15

This is what I did so far

Tell me what you think. It's still rather slow though. And very primitive and clunky. But it works (I think).

scimonster · 2011-04-01 03:36:36

Um, it didn't solve anything. hmm
Maybe we need to invent some special characters to mean multiple character things.

You would WANT it to go like this:

1 + (2 - (3 + 4))
1 + (2 - 7)
1 + -5
-4

True. Actually, that's a good idea!

@hpotter134, that engine is a bit clunky. Did you mess with the setup engine?
