We all study the decimal number system since childhood, it is familiar and understandable to us. Questions arise when we need to translate a number written in decimal notation into a system with a different base. I was recently asked how I explained this translation of units to children, they took this topic as part of a computer science course. The number system is one of the key concepts in computer science that you need to know when studying information technology. This is the foundation on which everything else is built. Without understanding what it is, in the future it will be quite difficult for you. Therefore, it's time to figure out what the number system is. In the decimal system, we use ten digits. These are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. When we reach the last number 9, then we go to a new digit - ten. The counting starts at 10 and continues on at 11, 12, 13, and so on. When we again reach 9 in the last digit of the digit, in this case up to 99, then we go to hundreds. The counting starts from one hundred - 100 and continues with 101, 102, 103 and so on. Again we reach the last number of the hundredth place, 999, add 1 and the thousandth place begins - 1000, 1001, 1002 and so on. So ad infinitum. Consequently, the last digits in the ten, hundreds, thousand places are 99, 999, 999, respectively.

Hexadecimal number system is a positional integer number system with base 16. It is one of the most popular in computer science, along with binary, octal and decimal. The hexadecimal number system began to be widely used with the development of computer technology. As you know, computers use binary code. But its use is inconvenient, due to long entries, and it took a lot of time and memory to convert to the decimal system. 16 is a multiple of two, so the calculations were faster. Number systems are one of the most important foundations of computer science. Almost no school or university skips this topic, but often it is with the translation of the hexadecimal system that many have problems, although this is not such a difficult task, and its translation is practically no different from other number systems.
