This was extremely informative. Very basic but you went over the details of the functions and how they are working in a manner that allowed me to actually learn from your work. Don't let anybody tell you their work is better, when you clearly understand what is happening from your work so well.

}
function sum()
{
setValues();
result = a+b;
alert("The sum is equal to"+result);
}
function rest()
{
setValues();
result = a-b;
alert("The rest is equal to"+result);
}
function multiply()
{
setValues();
result = a*b;
alert("The operation is equal to"+result);
}
function div()
{
setValues();
result = a/b;
alert("The operation is equal to"+result);
