Simplify equations like (1 - ((1 - (i/10)) / (1 - (i/10))))

[Artur Rataj]

(1 - ((1 - (i/10)) / (1 - (i/10)))) would be evaluated to 0 etc.

At least your example listed above works in the current Java 8 sources.

See MainTestCase#testSystem000b() JUnit test case.

That's great. In an unrelated application Symja did not simplify the following to 0:

    util.evaluate("d-d*x1-c/(d*x1)+(c*d)/(d*x1)+(-c*d^2*x1)/(d*x1)+(c*d^2*x1^2)/(d*x1)+x3/(d*x1)+(-d*x3)/(d*x1)+(d*x1*x3)/(d*x1) - " +
            "( -(c-c*d-d^2*x1+c*d^2*x1+d^2*x1^2-c*d^2*x1^2-x3+d*x3-d*x1*x3)/(d*x1) )");

but I needed it just once for debugging, so not a problem for me.

It seems that I can not close this issue, though.
