Different number systems are available on the basis of their base numbers. For instance, decimal number system is of base 10, hexadecimal number system which base is 16 and, Binary number system which base is 2 etc. Some numbers systems are easy to understand by the human being and some are easy to understand by electronics machine for instance digital computers. Computers only can understand data and instructions that are stored in binary form, though we input the data and instruction in decimal, text, audio, and video or image forms. So it is very crucial for people who are interested or working in the field of science and engineering to learn decimal to binary conversion and vice versa. In this article we represent a new scenario with an algorithm, how to learn or finding a concept of binary number system for those who just have the idea of decimal number system.
