Performing calculations, counting in Binary and Fibonacci Sequence

The formula used to return a whole number doing division is "%".
The "/" sign gives you the full answer. To get a whole number you have to use "//". I used the "%" to get the remainder of the question.
I have included an example below:

We use the binary system to make it simpler to use than the decimal system in computers and technologies. It's important to understand the binary system because it's the main counting system computers use.

It goes like this:

0110010101

There are no numbers in the binary system except 1 and 0.

An example of how binary works:

128 64 32 16 8 4 2 1

0    0   0  0  1  0 0 1 0

This equals to 18, because there is a "1" under 16 and 2. 

Here are some examples of Fibonacci in nature:
