bug with MathObjects reduction

[Alex-Jordan]

We've hit a bug with a reduction rule in MathObjects. Something like -5/(-2x) is incorrectly reducing to 5/2*x. Here is a MWE.

DOCUMENT();

loadMacros(
  "PGstandard.pl",
  "MathObjects.pl",
  "PGML.pl",
);

TEXT(beginproblem());

$answer = Formula("-5/(-2 x)");
$reduced = $answer->reduce;

BEGIN_PGML

The answer is [$answer], which reduces to [$reduced].

END_PGML

ENDDOCUMENT();

(I'm having trouble logging in to the forum while the transition is underway, or else I might have posted this there.)

You need to do a password reset on the wiki. After you do that you will be able to sign in to the wiki and the Moodle forums. Go to https://webwork.maa.org/wiki/Special:PasswordReset to do this.

Glenn,
Do you know if the emails for password reset are being sent out by the wiki?

[drgrice1]

I am not sure. I was hoping so. I will look into it.

It seems that the password reset emails are not being sent (or at least received).

When I request a password reset email it is sent and caught in our spam filter, likely because it came from apache@🌻.invalid (see openwebwork/webwork.maa.org#29).

This is still a bug (just tested on develop). The wiki login discussion may have distracted from the issue I reported.

I have made a PR (#546) that addresses this issue. Sorry for the long wait for it. It has scrolled off the top of my email screen, where I don;'t often look, and so was in limbo until I cleared out some more recent items.
