The binary system is a numerical system that functions almost exactly like the decimal system, which most people are more familiar with. The base number for the decimal system is 10, while the binary system uses 10. The binary system uses 2, whereas the decimal system uses 10, while the binary system uses 1, which is called a bit. These differences aside, operations like addition, subtraction, and multiplication are all calculated using the same rules as in the decimal system.
Because of its simplicity in implementation in digital circuitry with logic gates, almost all modern technology and computers use the binary system. It is easier to design hardware that can detect only two states (on and off, true/false, or present/absent) than to see more states. Hardware that can detect ten states using a decimal system will be required, which is more complicated.
Here are some examples of conversions between decimal, hex, and binary values:

How to convert decimal to binary

You can convert the decimal system to the binary system by following this step-by-step procedure:
Find the largest power between 2 and the given number
Add that value to your given number
Find the largest power between 2 and the remainder in step 2
Continue repeating until there is no more
Enter a 1 to indicate the binary place value. A 0 indicates that there was no such value.

How to convert binary to decimal

Every position in a binary number represents a power of 2 just like every position in decimal numbers represents a power of 10.
In order to convert binary to decimal, you will need to multiply each position by 2 to the power number of the position number. This is done by counting from left to center and starting with zero.

Binary Addition

Binary addition follows the same rules as the addition in the decimal method except that; instead of carrying a 1, when the values added equal 10, a carry-over occurs when the result is branch equals 2. 
The only difference between binary and decimal addition is that the binary system's value 2 corresponds to the decimal system's equivalent value of 10. You will notice that superscripted 1,s denote digits that have been carried over. When performing binary addition, a common mistake is when 1 + 1 = 0. Also, 1 from the previous column to its left has a 1 that was carried over. The value at the bottom should then be 1 instead of 0. In the example above, you can see this in the third column.

Binary Subtraction

Similar to binary addition, there is not much difference between decimal and binary subtraction, except those caused by using the digits 1 and 0. Borrowing can be used when the number being subtracted is greater than that of the original number. Binary subtraction is where one is removed from 0. This is the only instance in which borrowing is required. When this happens, the number 0 in the borrowed column becomes "2". This transforms the 0-1 to 2-1 = 1 while reducing 1 in the column being rebought from by 1. If the following column has a value of 0, borrowing will need to be done from all subsequent columns.

Binary Multiplication

Binary multiplication can be simpler than decimal multiplication. Binary multiplication is simpler than its decimal counterpart, as there are only two values. Noting that each row has a placeholder 0, the result must be added and the value must be shifted to the right, much like decimal multiplication. Binary multiplication's complexity is due to tedious binary addition that depends on how many bits each term contains. See the example below to see more.
Binary multiplication is exactly the same process as decimal multiplication. You will notice that the 0 placeholder appears in the second row. In decimal multiplication, the 0 placeholder is typically not visible. The same thing can be done in this case, but the 0 placeholders will be assumed. It is still included because the 0 is relevant to any binary addition/subtraction calculator like the one shown on this page. If the 0 was not shown, it is possible to ignore the 0 and add the binary values above. It is important to note that the binary system considers any 0 right of a 1, while any 0 left is irrelevant.

Binary Division

The binary division is similar in process too long division using the decimal system. The dividend is still done by the divisor in exactly the same way. The only difference is that the divisor uses binary subtraction instead of decimal. For binary division, it is crucial to understand binary subtraction.
