Number System : Base concept

CAT (common admission test) always checks your thinking out of the box ability. Today what we shall discuss proves this unparalleled ability of CAT. GRE and GMAT have also used this concept. But most of the books have ignored this topic. But I really can't figure ou why? This concept is being repeatedly put to test several times. And topic is too easy even.



As we all know that we follow decimal number system. But have you ever wondered that can there be other number system too. Say octagonal number system. Have you ever wondered why anything raised to zero is one? If you know this well and good. But if you don't know this....we shall discuss this today.


Tomorrow I am going to post a slideshow with few questions on the concept that we discussed today. 
That is it for today! Thank you!
