Given following
Exercise 1: Calculate 4+1-(2-5)
Check Solution
After a short calculation we think the solution might be
8. The solution is not given, only the above link. It leads
to SolutionChecker, you enter 8 and you are confirmed that
your solution is indeed correct. Every other number or other
input does not give you "Correct".

How to generate a SolutionURL

Given a webauthor who poses one or many exercises which are
to be solved by one or many visitors of her page. The
solution is not to be revealed directly, for a specific
guess one should be given only the answer "WRONG" or
"Correct", respectively.
Webauthor goes to Solution generate and types the number of
the Exercise and the correct solution. After that the button
"generate URL" generates a URL in the text
field below. The webauthor cuts and pastes this url into her
own text for a checkSolution link.
Be careful with the solutions! First of all they should be
double checked whether they are really really correct. You
may use non-integers as solutions like 3.14, 3/4 or any
other string like {1,8,"apple pie"}. However, be afraid
that the solution must be EXACTLY like that. (with the
ONLY exception of blanks) Therefore, clearly define in the
problem to what precision a non-integer number should be
given. Also exercise number can be non- or half-numeric like
A.1.f where blanks are ignored.
