I have a list, it contains (for example) 567+9-sinx/5
How do I translate the equation from the list, all into one equation on one block
like this

when I receive [turn into equation v]
put in scripts to help turn into one equation here
set [variable v] to <<[567]+[9]>-<<[sin v] of <x>>/[5]>>

please help!

You're going to have to use a script that looks a little something like this first:

when I receive [turn into equation v]
set [# v] to (0)
repeat (length of (answer))
  change [# v] by (1)
  if <[symbols] contains (letter (#) of (answer))>
    add (letter (#) of (answer)) to [ops v]
  else
    if <(last) = [Num]>
      replace item [last v] of [numbers v] with (item)
    else
      add (letter (#) of (answer)) to [numbers v]
    end
  end
end

Sorry...not quite finished, I have other stuff to do, sorry. Hopefully this at least helps a bit!

What does symbols contain?
If someone can please explain this script to me and what it does, that would be helpful. I barely (if not at all) understand the scripts that I already make.

The best way I can describe it is with my own project tongue . Read the scripts, it's easier programming then reading them though hmm

Easier to understand

Harder to understand

Thank you, I'll bump again if I don't know what to do.

Symbols would be a preset list you make containing the items:
+
-
*
/
^
(
)
then you can label each symbols "importance" in another list for PEMDAS to work...sorry, it's complicated, but could work.

I actually found a method (using laptop97's project). It will be based off of that, but a little more complicated since I am building a "grapher" project that one of the options for a graph is an equation.

Well, using an idea from laptop97's project I was able to finish one part of it. You can look at it here. Although some of the scripts will be kind of hard to understand.
