Binary

All you need to know about Binary!!

What is Binary?

Using or denoting a system of numerical notation that has 2 rather than 10 as a base.

How to convert binary to denary

The binary numeral system has two possible values, often represented as 0 or 1, for each place-value. In contrast, the decimal numeral system has ten possible values (0,1,2,3,4,5,6,7,8, or 9) for each place-value.

How to add binary numbers together

Adding two binary numbers together is like adding decimal numbers, except 1 + 1 = 10 (in binary), so you have to carry the one to the next column:

0001

+ 0100

0101

Addition with limited bits

The addition problem on the left did not require any bits to be carried, since the sum of bits in each column was either 1 or 0, not 10 or 11. In the other two problems, there definitely were bits to be carried, but the process of addition is still quite simple.
