Display or conceal a div depending on the value of an integer stored in the $scope variable

Consider the ng repeat pattern below:

<div class="presentForm" id="presentForm{{$index}}"  ng:repeat="slide in slides" style="display: block;">
                <img id ="presentationSlide" ng-src='{{slide}}' style="height: 300px" width="600px">
                <label id="scriptLabel{{$index}}" for="slideScript{{$index}}" style="left:130px;">Slide {{$index + 1}} Script</label>
                <textarea class="scriptText" name="Text" id="slideScript{{$index}}">'{{slide.script}} </textarea>
            </div>

My current query revolves around displaying a specific id="presentForm{{$index}}" element when {{$index}} matches an integer stored in a variable named $scope.display. I am seeking guidance on how to achieve this using angular expressions, especially when dealing with a non-Boolean variable.

The ng-show/ng-hide attribute allows for the evaluation of an expression that results in a boolean value.

For example, you can use ng-show="$index == display":

<div class="presentForm" ng-show="$index == display" id="presentForm{{$index}}"  ng:repeat="slide in slides" style="display: block;">
            <img id ="presentationSlide" ng-src='{{slide}}' style="height: 300px" width="600px">
            <label id="scriptLabel{{$index}}" for="slideScript{{$index}}" style="left:130px;">Slide {{$index + 1}} Script</label>
            <textarea class="scriptText" name="Text" id="slideScript{{$index}}">'{{slide.script}} </textarea>
