Simple calcul mathématique à l'aide de jquery

C'est mon code et je veux l'utiliser en appuyant sur les touches du clavier et de la solution simple pour la même volonté d'être utile. je devrais aussi être en mesure d'effectuer plusieurs calculs. pour eg.
2+2+ -> 4+2+ -> 6+2= ->8.

Html:

<div id="main">
<h2>Simple Calculator</h2>
<input id="Result" type="number" />
<div id="keys">
<div id="FirstRow">
<button id="ClearAll" type="reset" value="CE" class="clean">CE</button>
<button id="Clear" type="reset" value="C" class="clean">C</button>
<button id="Add" type="button" value="+" class="operators operand">+</button>
</div>
<div id="SecondRow">
<button id="One" type="button" value="1" class="Show">1</button>
<button id="Two" type="button" value="2" class="Show">2</button>
<button id="Three" type="button" value="3" class="Show">3</button>
<button id="Sub" type="button" value="-" class="operators operand">-</button>
</div>
<div id="ThirdRow">
<button id="Four" type="button" value="4" class="Show">4</button>
<button id="Five" type="button" value="5" class="Show">5</button>
<button id="six" type="button" value="6" class="Show">6</button>
<button id="Mul" type="button" value="*" class="operators operand">*</button>
</div>
<div id="FourthRow">
<button id="Seven" type="button" value="7" class="Show">7</button>
<button id="Eight" type="button" value="8" class="Show">8</button>
<button id="Nine" type="button" value="9" class="Show">9</button>
<button id="Divide" type="button" value="/" class="operators operand">/</button>
</div>
<div id="FifthRow">
<button id="Zero" type="button" value="0" class="Show">0</button>
<button id="Dot" type="button" value="." class="Show">.</button>
<button id="Calculate" type="button" value="=" class="operand">=</button>
</div>
</div>
</div>

JQuery:

$("document").ready(function () {
var key = null;
$(".clean").click(function () {
$('input').text("");
});
$(".Show").click(function () {
var EText = $('#Result').val();
if (EText != "0") {
var val1 = EText;
var ButtonVal = $(this);
var val2 = ButtonVal.text();
var Res = val1 + val2;
$('#Result').val(Res);
} else {
$('#Result').val()
}
});
$(function () {
var interRes = null;
var operator;
$('.operators').click(function () {
var value1 = $('#Result').val();
if (interRes != null) {
var result = ApplyOperation(interRes, value1, operator);
interRes = result;
} else {
interRes = value1;
}
operator = $(this).text();
$('input').val("");
});
$('#Calculate').click(function () {
var op = operator;
var res;
var value2 = $('#Result').val();
if (value2 != "") {
res = ApplyOperation(interRes, value2, op);
} else {
res = interRes;
}
$('#Result').val(res);
interRes = null;
});
});
function ApplyOperation(value1, value2, operator) {
var res;
switch (operator) {
case "+":
res = addition(value1, value2);
break;
case "-":
res = subtraction(value1, value2);
break;
case "*":
res = multiplication(value1, value2);
break;
case "/":
res = division(value1, value2);
break;
}
return res;
}
function addition(first, second) {
var a = parseFloat(first);
var b = parseFloat(second);
var total = a + b;
return total;
}
function subtraction(first, second) {
var a = parseFloat(first);
var b = parseFloat(second);
var sub = a - b;
return sub;
}
function multiplication(first, second) {
var a = parseFloat(first);
var b = parseFloat(second);
var product = a * b;
return product;
}
function division(first, second) {
var a = parseFloat(first);
var b = parseFloat(second);
var divi = a / b;
return divi;
}
});
