Cara Membuat Kalkulator Html dan Javascript

- Langkah pertama anda buka notepad /dreamweaper /apa saja untuk mengelola copy script di bawah ini yang berwarna merah :
<html>
<head>
<title>4 operator perhitungan</title>
</head>
<script language="Javascript" type="text/javascript">
<!--
function nilai()
{
if(operator.value=='*')
{c.value=eval(a.value)*eval(b.value);}
else if (operator.value=='/')
{c.value=eval(a.value)/eval(b.value);}
else if (operator.value=='+')
{c.value=eval(a.value)+eval(b.value);}
else if (operator.value=='-')
{c.value=eval(a.value)-eval(b.value);}
}
function kosong()
{
form.a.value=""
form.b.value=""
form.c.value=""
form.operator.value="--choose--"
form.a.focus()
}
//-->
</script>
