If you know the number base, you know the number of values for each digit in a number, and you can also determine the value of the digits to the left of the least significant digit in a number. Remember this: the lefmost digit of any number is the most significant digit; the rightmost digit is the least siginificant digit of the number. So, in a number such as 107, the one is the most significant, the seven is the least significant digit.
Lets look at number base comparisons: Lets take a common number: 256 base 10.
Base 10: 2 x 100 + 5 x 10 + 6 x 1 = 200+50+6 = 256 (Base 10)
Base 2: 2(8th) = 256 + 0x128 + 0x64 + 0x32 + 0x16 + 0x8 + 0x4 + 0x2 + 0x1 = 100000000 (Base 2)
Base 16: 16(2nd)= 256 + 0x16 + 0x1 = 100 (base 16)
Hmmmm.
