independent conditions Jquery,javascript

How can I set "independent conditions" in jQuery? I have 13 different possibilities and I just want to execute them independently of each other in my program, here is my code;

$('#account-form1 input#odenen,#account-form2 input#odenen').one("blur",function(){

        var bakiye = parseFloat($("#bakiye").val());
        var borcu = parseFloat($("#borcu").val());
        var odenen = parseFloat($("#odenen").val());
        var alacak = parseFloat($("#alacak").val());


        // 1.possibilty
        if((borcu == 0) && (odenen > bakiye)){
            var current_alacak = parseFloat($('#alacak').val());
            $('#alacak').val(current_alacak + (odenen - bakiye));

        // 2.possibilty
        }else if((borcu > odenen) && (bakiye > odenen)){
            var current_borcu_2 = parseFloat($('#borcu').val());
            $('#borcu').val((current_borcu_2 - odenen) + (bakiye));

        // 3.possibilty
        }else if((borcu > 0) && (borcu < odenen) && (bakiye > odenen)){
            $('#borcu').val(bakiye - (odenen - borcu));

        // 4.possibilty
        }else if((borcu > 0) && (odenen > (borcu + bakiye))){

            var current_alacak_2 = parseFloat($('#alacak').val());
            $('#alacak').val(current_alacak_2 + (odenen - (bakiye + borcu)));
            $('#borcu').val(0);

        // 5.possibilty
        }else if((borcu > 0) && (borcu < odenen) && (odenen > bakiye)){
            $('#borcu').val(bakiye - (odenen - borcu));

        // 6.possibilty
        }else if(odenen < bakiye){
            var current_borcu = parseFloat($('#borcu').val());
            $('#borcu').val(current_borcu + (bakiye - odenen));

        // 7.possibilty
        }else if((borcu > 0) && (odenen = (bakiye + borcu))){
            $('#borcu').val(0);

        // 8.possibilty (this one is not working right because of another condition)
        }else if((borcu == 0) && (alacak > 0) && (bakiye = (odenen + alacak))){
            $('#alacak').val(0);
        }  
                     ***goes on like this..***

Conditions may executing same time and affecting result :/
