What is the Binary Number System and how does it work? This is one of the numerous questions many learners of basic Maths are likely to ask.

Years ago when civilisation started, humans discovered a number system that has exactly ten digits.

My article on the History of Numbers briefly describes the origin of counting and numbers.

The 10 digit number system was called Decimal Number System, from the Latin word ‘decimus’ meaning tenth, and as we may know, the digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The system has its base as 10.

Shall we have a little recap on how it works so we can apply in our studies on binary numbers?

Not so long ago, another number system also became famous in the language of computers.

This system got the name Binary numbers, using only two digits; 0 and 1.

The binary number system became necessary because early computers had simple circuits that act like ordinary light switches which turn on (1) and off (0).

Binary numbers operate on base 2 and so their digits increase in the powers of 2; contrary to base ten number system.

With the same knowledge of representing base 10 numbers, we can represent numbers with base 2 number system.
