Hi all,

I'm teaching Microworlds Pro and my students are running up against a
problem I'm also stumped by. They are asking math questions with the
primitive "question", then testing the "answer" with ifelse, like so:

Question [how much is 2 + 2 1/2?)

Ifelse answer = [4 1/2] etc.

Here's the problem -- entering 4 1/2 (with the space) is counted as a wrong
answer. Using double quotes ("4 1/2) also doesn't work, because "answer"
only takes the first number (4). And ["4 1/2] doesn't work either.

I'm sure it's something simple, but I can't find the syntax in the docs.

TIA,
