In base 2 for exemple (mostly use in computer science in pair with base 16) there is only 2 digits : 0 and 1 so the number 5 will be 101 in 2 digits base. why? 1*2^0 + 0*2^1 + 1*2^2 = 5 Now, in bases over 10 the necessity of making more symbols are obvious. So, in base 100 there will be 100 diferent digits. In this case the youtube video that you post explains the process of memorizing the symbols and i founded it realy interesting. Hope i explained you in a way you understand Ohh, just a curiosity: Why we have base 10 for default? Because in the past it made it easy to count by the fingers of the hand __________________ You need only 2 objectives in life: when you look at the past and you say that you coudn't have done any better than that is the 1º one. The 2º one is to do better than that Then, you must learn 2 rules in your life: Rule number one : respect yourself and the others Rule number two: first learn rule number one
