               DIGITAL DESIGN EXAM TIPS

  1. Don't worry if you didn't attend all the lectures.[I'm sure you will not understand anything anyway :)]
  2. Try not to read from the lecture slides (from experience)
  3. Better to read from the text book itself.It explains many concepts (because your lecturer can't and that is why you are reading this article!!)
  4. Better to start reading from at least a week before the finals if u plan to do it from text book
  5. Start from the middle of the book(that is from where the important things start.You won't be asked about bits and bytes in the exam anyway)

THE GAME OF FOUR FOURS

           GAME OF FOUR FOURS 


RULES:
The rules of the game are very simple.You just have to use '4' four times and have to construct the integers 0,1,2,3..... , etc

The valid Operations one can use are
  • You can surely use the four fundamental operations of mathematics (+,-,X,/)
  • Concatenation is valid (44,444 are perfectly fine)
  • Powers can be used (4^4 is perfectly sound)
  • You can use square roots  ( √ )
  • You can use the factorial operation  (4! = 4 X 3 X 2 X 1 = 24)
  • You can use the decimal form also ( .4 is valid)
