** Using WeBWorK **

We recently got a series of error messages from many problems that all involve calls the Sage for computations. It seems the returned values are not getting converted to the proper format in Perl.

ERRORS from evaluating PG file:
 Can't use '*' with String-valued operands at line 110 of (eval 644)
 examination indicates the error is because $real and $imag are now string variables
did something change recentsly
