Number System - Base System - 1 of 2

In these two videos we talk about how to convert numbers in the decimal system to some other base and vice versa. We also discuss how many zeroes will be there at the end of a number in a different base. We also talk about adding, subtracting and multiplying in a different base.

These videos belong to the Number System section of Quantitative Aptitude for the Common Admission Test (CAT).

Even though base 16 can be divided by 2 four times and a good way to represent binary, unfortunately, it is divisible by no other prime number. Base 12 is a lot better than base 16 because even though it is not superior to base 16 in "a binary way", it is divisible by 2 prime numbers, 2 and 3, unlike 16 has only 1 prime factor, 2.

when you were converting the bases from letter form to number you stated that F was 15 and that H was 16. But if that is so then what is G? in an alphabetical aspect that doesnt make sense. shouldnt F=15 and G=16 and H=17 ?
