javascript - i can remove width/height correctly but not add width/height correctly

Question

I tried for like 15 mins now and for some reason adding is different then removing

function ImageSize(n)
{
    image = document.getElementById("img2");
    var width = image.getAttribute("width");
    var height = image.getAttribute("height");
    if(n == 1)
    {
        image.setAttribute("width",(width + 10));
    }
    else if(n == 0)
    {
        image.setAttribute("height",height - 10);
    }
}

the - 10 works perfectly, but when I try to add 10 it adds like a thousand
