    Surprising! isn't it? In the decimal counting system, we count 1, 2, 3, 4, 5, 6, 7, 8, etc... In binary, you simply count using numbers that have only 1s and 0s. That gives 1, 10, 11, 100, 101, 110, 111, 1000, etc... This system is widely used in Informatics/Programming.Binary is a counting system using 2 as a base .This means that place values are define by 2^n, as opposed to 10^n in decimal.This also means that in decimal (classic) numbers, 1+1=2 because:10^0 * (1)...

This is called the Conway Sequence _______________________ To find the answer, we must say the previous numbers. For example, for one, we will have one 1. This becomes 11. For 1211, there is a 1, a 2 and two 1. This gives 111221.   That gives the result as follows: 1 - 11 - 21 - 1211 - 111221 - 312211 - 13112221 - ... _______________________
