I love contextScientificNotation.pl, but it forces students to use 'x' instead of '*' to represent the multiplication symbol. How can I redefine it?
Thanks!

so what I would do (and there is probably a much better way) is download a copy of the file contextScientificNotation.pl
https://github.com/openwebwork/pg/blob/master/macros/contextScientificNotation.pl
and put it in your macros file in "File Manager"
then edit around line 143
$context->operators->add(
'x' => {precedence => 3, associativity => 'left', type => 'bin',
string => 'x', TeX => '\times ', perl => '*',
class => 'ScientificNotation::BOP::x'},
'*' => {precedence => 3, associativity => 'left', type => 'bin',
string => '*', TeX => '\times ', perl => '*',
class => 'ScientificNotation::BOP::x'},
'^' => {precedence => 7, associativity => 'right', type => 'bin',
string => '^', perl => '**',
class => 'ScientificNotation::BOP::power'},
'**'=> {precedence => 7, associativity => 'right', type => 'bin',
string => '^', perl => '**',
class => 'ScientificNotation::BOP::power'}
);
and see if that works
Thank you both, Ryan and Davide!

While Ryan's solution would work, it would also mean that your problems would only work with your modified version of
contextScientificNotation.pl, and so would be less portable.
An alternative would be to do:
loadMacros("contextScientificNotation.pl");
Context("ScientificNotation");
Context()->operators->add("*" => Context()->operators->get("x"));
which will add the definition of * to be the same as that of x.
See yeah that's a smarter way =)
