In this lesson we are going to repeat some methods and put it all them together, which we already used into previous lessons. Some methods are difficult so we are going to use an example in 2 ways. Both methods are useful. 1st is in very simple way, 2nd is a little bit complicated for those students who enroll newly in this course or just started learning programing. Don't be afraid 2nd method is more useful than 1st, just give it to some extra effort to learn. In 2nd method the way of using code or keywords is going to be very useful in future for us.let see.
