  Ah, thanks for the info!

  I'm actually planning to write something like that myself.

  As a quick little trial run, I recently "implemented square roots".

  You can see three sample outputs here:

 .-
\|x

 .---
\|x+y

 .-
 |x
 |-
\|y

  A rectangular area made of characters is described by a "box":

class Box:
    __slots__=["content","width","origin","baseline"]
    def __init__( self, content, width, baseline ):
        self.content=content
        self.width=width
        self.baseline=baseline
        return
    def __str__( self ):
        return "\n".join(self.content)

  . The root class only has one method, "render_ascii_display",
  which generates a square root sign:

class Sqrt:
    def render_ascii_display( self, operand ):

        # add bar above
        content=["-" * operand_box.width]+operand_box.content

        new_content = []

        # add bar left
        for i, line in enumerate( content ):
            if i == 0:
                prefix = " ."
            elif i == len( content )-1:
                prefix = "\|"
            else:
                prefix = " |"
            new_content.append( prefix + line )

        content = new_content

        bar_box = Box(content, 2+operand_box.width,operand_box.baseline)

        return bar_box

  . Basically, it draws a line over the operand and another
  one to its left, with the top and bottom edges ending in 
  " ." and "\|" to form a square root sign.

  Since the classes for variables, sums, and quotients aren't
  written yet, those operands are manually formatted in the
  main program for now:

sqrt = Sqrt()
operand_box = Box( ["x"], 1, 0 )
print(sqrt.render_ascii_display(operand_box))
print()
operand_box = Box( ["x+y"], 3, 0 )
print(sqrt.render_ascii_display(operand_box))
print()
operand_box = Box( ["x","-","y"], 1, 1 )
print(sqrt.render_ascii_display(operand_box))
print()

  . The output was shown above near the top of this post.
