code here just like going to github.

3 back ticks, new line, code, new line, 3 back ticks.

You probably just need to post your form, work out the answer in the controller, and display what you need to display on a new answer page.

Also I would highly suggest dropping the collective class and using regular blade and HTML. Many here has said the same including Jeffrey.

The code in that class just makes it harder to read.

Also for old value, which I think that's what you mean.

        <select class="form-control custom-select" name="operators" value="{{ Session::get('operators')}}">
                <option value="+" id="plus" name="plus" {{ Session::get('operators') == '+' ? 'selected' : '' }}>Addition (+)</option>
                <option value="-" id="minus" name="minus" {{ Session::get('operators') == '-' ? 'selected' : '' }}>Subtraction (-)</option>
                <option value="*" id="times" name="times" {{ Session::get('operators') == '*' ? 'selected' : '' }}>Multiplication (*)</option>
