    sec = 10;
    timer = setInterval(function() {
        $('#timerSec').text(sec--);

    }, 1000);
}
$(function() {
startTimer();

$('#btnGo').click(function(){
    $(this).fadeOut();
    $("#alert").fadeIn();
    clearInterval(timer);
    var secR = $('#timerSec').text();
    var t = $('#alert span').text()
    $('#btnCon').fadeIn();
    if (secR != 0 ){
    var i = t+1;
    }
    $('#alert span').html(i).show();
});
$('#btnCon').click(function(){
   $("#alert").fadeOut();
    $("#btnGo").fadeIn();
    startTimer();

I'm not sure it's functioning as you want it to, but in any case the problem with the addition is that it was treating the text value of the span as a string (which it is). So when you "added" 1 to it, it was actually just concatenating. You can use Number() to fix this. See this updated code.
