So I understand, do you want a calculator?

var content = document.querySelector("#content");
for(var i=0;i<10;i++){
  (function(){
    var div = document.createElement("div");
    var input1 = document.createElement("input");
    var input2 = document.createElement("input");
    var result = document.createElement("span");
    input1.oninput=input2.oninput=function(e){
      result.innerHTML = Number(input1.value)*Number(input2.value);
    }
    div.appendChild(input1);
    div.appendChild(document.createTextNode(" x "));
    div.appendChild(input2);
    div.appendChild(document.createTextNode(" = "));
    div.appendChild(result);
    content.appendChild(div);
  })();
}

<span id="content"></span>
