can i help? I'm good at math. I can make it calculate x^y, by 10^(y*log(x)) or e^(y*ln(x))
EDIT: why are the blocks showing up and the text in bold?[/blocks]

Code:

10^(y*log(x)) or e^(y*ln(x))

Type in a code box 

You needed an /blocks or else it didn't work in code. 

But I didn't even type in [ blocks ]

math, no

Can I be a tester? I'd also like to make some nice graphics for it, like a loading bar and stuff. When you're done I could stuff it into my applebasic program, and also we could make it into a GRAPHING CALCULATOR, the best one on scratch. Plus, with the flash turbo it could be AWESOME. Good news: I'm now an official app developer for apple, by the name of applejack apps XD I can't wait for the whole thing to download!!! Please let me join this collab since we're done with Virus (I think) If you don't say no I'll assume it's a yes and will start making graphics! Have a nice spring break! 

Sure, you can join! So, let's get started. Can someone whip something up to do the following to an input:

delete all spaces
replace sqrt with ' √ '
repelace [ ] and { } with plain old ( )

That ought to be the firs step, in my opinion.

I can help. My math knowledge is lot better than that of Scratch, if that helps. (I still know a reasonable bit of Scratch though.)

What now?
I can work on some basic functions.

So will I.

Have Succesor (if he's working on this, i forgot) build us a stack frame.
I'm terrible at the start.

P.S. Edit: He's good at it. He knows plenty about it.

Some graphics for the background of the calculator are here. Remember, there are more than just one! (see them in the experimental viewer).

Are we even going to try to put OOO in this?

1) Order Of Operations
2) "cna"? 
3) Thank you!
4) OK, I like the name.

We have two choices:

1: First, eliminate all brackets, then solve a bracketless expression.
2: Add brackets to it until it is fully bracketed, then simplify.

eg:

To solve 7+3(3+2)

1: solve 7+3*3 + 3*2
2: solve 7+ (3*(3+(2))

I vote for 1, because we'll get stuck if we get (1+2)(3+4) in 2.

I like 1 better.

OK. What now?
Start solving it. 

The reason it would be so much easier in BYOB is recursion. Here if we do a broadcast like "parentheses" to solve what's in it, if there is parentheses in the parentheses, it wouldn't work.
