ng-show= " true "但仍然有class= " ng-hide "

I'm new to AngularJS, so there may be a simple resolution to my problem. I've been working on this form. I have two inputs - one is for the number of doors and one is for the number of windows. I then have several divs that I want to show if they meet a certain number of total doors and windows. When I enter numbers into the input, the ng-show resolves to "true". But the element still has the class of "ng-hide" on it which still leaves it hidden.I'm new to AngularJS, so there may be a simple
