Today we are going to learn about surds and radicals  in this blog post . Before beginning with 'surds and radicals' you should visit and revise the concepts of number system , NUMBER SYSTEM So, lets begin with surds and radicals Let x be a rational number and n be a positive number such that ⁿ√x is  irrational , then ⁿ√x is called a radical of order n or surd and here x is called the radicand. * A surd of order 2 is called quadratic surd, i.e. √2 * A surd of order 3 is called a cubic surd i.e. ³√5 * A surd of order 4 is called a biquadratic surd * A surd has no fraction under the radical sign . * The radicand has no factor with exponent n. * A surd is not equal to any surd of order lower than n. * ⁿ√x is a surd only if x is a rational and ⁿ√x is irrational. * When x is irrational or ⁿ√x is rational then ⁿ√x is not a surd.

Today we are going to study about the number system and how we can really play with the numbers. NUMBER SYSTEM The system of numeration employing then ten digits 0, 1,2,3,4,.....,8 ,9 is known as number system . A group of digits, denoting a number is called a numeral. A number may be a natural number , a whole number , an integer , a rational number , a real number etc.It is important to mention here that the above classification of numbers is not mutually exclusive, e.g. . An integer can also be a whole number or a natural number.

There is a saying , Mathematics gives you more analytics powers at hand . This is quiet true . Today we are going to tell you about , 5 CEOs who studied mathematics . According to some reports by the Education Department of United States, the people who study mathematics  or science have the highest rates of employment. And also having a mathematics degree , gives you more significance . According to some reports, jobs have grown 75% faster as because more and more math graduates were in the market and the students with such a degree were having a high probability of having a high paying job.

Today we are going to learn about the A rea and Perimeter of Plane Figures . These include various figures like, square , rectangle , quadrilateral , parallelogram , rhombus , trapezium , right angled triangle , isosceles triangle , scalene triangle, equilateral triangle , circle , circular ring , semi circle , quadrant of circle , area of sector , regular polygon , etc. All these are important plane figures and today we are going to study about their area and perimeter and how we can compute them easily . Tip : get a pen and paper and write each formula for five to six times so that you may easily remember the formulae of  area and perimeter of plane figures . So, lets begin ,

Hi in this blog post i am going to tell you , What are the best books for you to improve your mathematics, There are various people and they have different needs of what they want to read about , actually there needs depend upon may be what they are presently pursuing or what they want others to read. Here is my list of recommended best books for you to improve your mathematics , so that you may learn better . I have divided the whole things into categories so that it may get easier for you to get an idea of what book you want .
