                $('#add').on('click', function () {
                    $('.toAdd:eq(' + count + ')').show();
                    count++;
                });
            });

</script>

The answer of Outlooker is right but have some little bit error. when user will click on show button 4th time then your hide doesn't work as expected. So I just fix the chunk here and sharing with you guys.

Html Code:

<div class="toAdd">One</div>
<div class="toAdd">Two</div>
<div class="toAdd">Three</div>
<input type="button" value="show" id="add" />
<input type="button" value="hide" id="sub" />

Java Script Code:

/**
 * Hide all Content div
 */
$(".toAdd").hide();
/**
 * Total no of content div find out
 **/
var lengthDiv = $(".toAdd").length;
/**
 * Default count declare
 **/
var count = 0;
/**
 * Click on show button
 **/
$('#add').on('click', function () {
    if (count < lengthDiv) {
        $('.toAdd:eq(' + count + ')').show();
        count++;
    }
});
/**
 * Click on hide button
 **/
$('#sub').on('click', function () {
    if (count > 0) {
        count--;
        $('.toAdd:eq(' + count + ')').hide();
    }
});

Try this too 

<script type="text/javascript">
            $(document).ready(function () {
                $('.toAdd').hide();

                $('#add').on('click', function () {
                    $('.toAdd,.hidden').first().show().addClass( "shown" ).removeClass( "hidden" );
                });
                $('#sub').on('click', function () {
                    $('.toAdd,.shown').last().hide().addClass( "hidden" ).removeClass( "shown" );
                });
            });

Try

var $toAdds = $('.toAdd').hide();

var count = 0;
$('#add').on('click', function () {
    if (count < $toAdds.length) {
        $toAdds.eq(count).show();
        count++;
    }
});
$('#sub').on('click', function () {
    if (count > 0) {
        count--;
        $toAdds.eq(count).hide();
    }    
});

    $('#add').click(function(){
    $('div').each(function(key, value) {

            $(value).delay(key * 500).fadeIn(500);

        });});
        $('#sub').click(function(){
        $('div').each(function(key, value) {
