You can simply use a variable to refer to this and you can use that variable latter.
var calculation = function() {
var _this = this;
this.Add = function() {
alert('In Add function');
}
this.Subtract = function() {
var add = function() {
//want to access Add function here
_this.Add();
}
add();
}
};
var cal = new calculation()
cal.Subtract()3 Comments

@BhojendraSah,
this.Subtract = function() { and OPs this.Subtract(){

It would be nice to stick to convention with captialisation of constructor and method names.

Personally I only would use
var _this = this; when using this in the function. Otherwise I'll use the bind method. See my answer.Try this:
vvar calculation = function(){
this.Add = function(){
alert("test");
}
this.Subtract = function(){
this.Add();
}.bind(this)
}
var sum = new calculation();
sum.Subtract();

That code is littered with syntax errors, and
bind is core JavaScript, it doesn't come from jQuery.Satpal

Sorry, did the coding a littlebit too quick. Edited my answer.
