ر کجا که میخوای این ماشین حساب رو قرار بدید ابتدا کد زیر رو قبل از تگ </head> قرار بدید:

 

                <style>

</style>

 

 

و این کد رو هم اون قسمت قالب که میخواین قرار داده بشه قرار بدید:

 

                        <div id="calculator">
	<!-- Screen and clear key -->
	<div class="top">
		<span class="clear">C</span>
		<div class="screen"></div>
	</div>
	
	<div class="keys">
		<!-- operators and other keys -->
		<span>7</span>
		<span>8</span>
		<span>9</span>
		<span class="operator">+</span>
		<span>4</span>
		<span>5</span>
		<span>6</span>
		<span class="operator">-</span>
		<span>1</span>
		<span>2</span>
		<span>3</span>
		<span class="operator">÷</span>
		<span>0</span>
		<span>.</span>
		<span class="eval">=</span>
		<span class="operator">x</span>
	</div>
</div>

		// Basic functionality of the calculator is complete. But there are some problems like 
		// 1. No two operators should be added consecutively.
		// 2. The equation shouldn't start from an operator except minus
		// 3. not more than 1 decimal should be there in a number
		
		// We'll fix these issues using some simple checks
		
		// indexOf works only in IE9+
		else if(operators.indexOf(btnVal) > -1) {

			// Get the last character from the equation
			var lastChar = inputVal[inputVal.length - 1];

			// Replace the last operator (if exists) with the newly pressed operator
			if(operators.indexOf(lastChar) > -1 && inputVal.length > 1) {

				input.innerHTML = inputVal.replace(/.$/, btnVal);
			}
			
			decimalAdded =false;
		}
		
		// Now only the decimal problem is left. We can solve it easily using a flag 'decimalAdded' which we'll set once the decimal is added and prevent more decimals to be added once it's set. It will be reset when an operator, eval or clear key is pressed.
		else if(btnVal == '.') {
