Binary Numbers

Previously we have discussed about how to solve limits and In today's session we are going to discuss about Binary numbers that comes under board of ssc education andhra pradesh, It deals with only two numbers 0 and 1.it is also known as base-2 number system. It has a radix of 2. In todays gadgets and computers, the circuits are implemented using binary coding that uses Binary Numbers.The main reason is that it is easy to manipulate the equations with 0 and 1.
We can define Binary Numbers as the ones that contain only two digits: 0's and 1's.
00000011001011011101010111 is a binary number. We can define Binary numbers as a sequence of 0's and 1's. The binary number can be converted into decimal numbers and hexadecimal numbers using the conversion formulas. Any number can be represented in the form of 0 and 1 and can be converted back into its original form .
Counting in binary number starts by taking rightmost digits and moving toward left. Conversion of binary number can be converted to decimal number by multiplying each digit by the corresponding power of 2.
for example,

0 0 1 1 can be converted to decimal number as,

[ 0 0 1 1 ]2 =[ ( 20 * 1 ) + ( 2 1 * 1 ) + ( 22 * 0 ) + ( 23 * 0 ) ]10
= [ 1 + 2 + 0 + 0 ]10
=[3]10

Similary, we can convert any binary number to a decimal number.
Following is the table which shows binary numbers and their corresponding decimal numbers.

Binary number decimal number

0 0
1 1
1 0 2
1 1 3
1 0 0 4
1 0 1 5
1 1 0 6
1 1 1 7
1 0 0 0 8
1 0 0 1 9

Now. Let us do addition in of binary numbers.
There are following rules,
1 + 1 =1 0
1 + 0 = 1
0 + 1 = 1
0 + 0 = 0

let us add two binary numbers,

1 0 1 0 + 1 1 0 0

1 0 1 0
+1 1 0 0
---------------------------------------------
1 0 1 1 0

we can implement a binary adder using this rule.
In the next session we are going to discuss Properties of Irrational Number and Read more maths topics of different grades such as Binomial Theorem
in the upcoming sessions here and You can visit our website for getting information about Normal Distribution Examples.
