    function checkoptions(){
        jQuery("#product-options-wrapper select option").each(function(){
            var optiontext = jQuery(this).text();

            if(addsignpos>0){
                var result = optiontext.substring(0,addsignpos-1);
                jQuery(this).html(result);
            }

            if(subtractsignpos>0){
                var result = optiontext.substring(0,subtractsignpos-1);
                jQuery(this).html(result);
            }
        });
    }

});
</script>

Replace the id and class as you using in site.

Through code also you can  change but their you  need to do changes in many files, the best and easy way to use the jquery script ;)
