We cannot imagine a world today without computers and they use to run the binary language. This language just can be created with two elements, positive and negative. It is logical, if we think that the computers have only two resources, entrance or not of energy.
The binary digits make up of the binary language, are codes formed with the power of two. Here what matters is the position. The first number of the serie is two raised to the power of cero, making it one. If one is included in the digit to set, the first position in the series is positive. The second and third number of the serie are two raised to one and two, making it two and four respectively. Then, you have to add the all the positive positions. If you want to create the number three in binary code, you must put positive the first and second position and add one and two which is equal to three. In binary language, positive is one and negative is cero, so three is 110. Of course the series of numbers that computers use are astronomical.
In binary language, positive can also be white and black negative. If you think about it, understanding that each position in the series corresponds to a time N, where N is the exponent of two, thus has the most primitive fractal which can create any positive number since zero.
