Properties of Irrational Numbers

Previously we have discussed about factoring perfect square trinomials worksheet and In today's session we are going to discuss about Rational and irrational numbers which comes under board of andhra pradesh intermediate, They are the different type of number representation in the number system of mathematics. These are the number representations which help in solving the problem related to math. If we define the rational numbers then we can say that rational numbers are those numbers which represent the integer value in the form of numerator and denominator. For example, x / y, here x is numerator and y indicates the denominator which should be greater then 0.

In the same sense we can say that irrational numbers are those numbers which can’t be represented in the form of numerator and denominator format. In the general sense irrational numbers in the number system can be considered as real numbers but they can’t be shown in fractional format. The fundamental properties of irrational number is that they can’t be represented in ratio form.Through this topic we are going to discuss about the Properties of Irrational Numbers. Let's explain the concept to you with the help of some examples.

The famous example of irrational numbers is ∏. Generally this symbol is known as ‘ pi ‘. In the mathematics pi value is approximated as 22 / 7. It means ∏ = 3.141592653589 and so on. In the value of pi , we can see that the value is not accurate or they can’t be represented in standard fractional format. Thus, one of the Properties of Irrational Numbers is that the cannot be represented in fractional form. (Know more about  Irrational Numbers in broad manner, here,)

Another famous example of irrational numbers are √2. In the √2 there actual value is 1.41421356 and so on. As like the another fractional number √2 can’t be represented using ratio property of two numbers and they can’t be represented in any simple faction. That’s why this is irrational number.

Even the number e (symbol of Euler number ) can’t be represented in the ratio form and in simpler fraction from.

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.
