ng-show   ng-hide accepts only boolean values   For complex expressions it is good to use controller and scope to avoid complications   Below one will work  It is not very complex expression   ng-show  User   admin     User   teacher     Here element will be shown in UI when any of the two condition return true  OR operation    Like this you can use any expressions

I generally try to avoid expressions with ng-show and ng-hide as they were designed as booleans  not conditionals   If I need both conditional and boolean logic  I prefer to put in the conditional logic using ng-if as the first check  then add in an additional check for the boolean logic with ng-show and ng-hide   Howerver  if you want to use a conditional for ng-show or ng-hide  here is a link with some examples  Conditional Display using ng-if  ng-show  ng-hide  ng-include  ng-switch

Use a controller method if you need to run arbitrary JavaScript code  or you could define a filter that returned true or false   I just tested  should have done that first   and something like ng-show   a  amp  amp  b  worked as expected

This will work if you do not have too many expressions   Example  ng-show  form type      Limited Company     form type      Limited Partnership    For any more expressions than this use a controller
