In mathematics odd and even numbers are very important concepts to understand. Without knowing the concept of odd and even number we can not understand the whole Algebra a branch of mathematics.  Firstly we will define Even numbers as a numbers are completely divisible by 2 and will get a remainder as 0 after division mathematical operation.  Whereas Odd numbers are not completely divisible by 2 and will not get a remainder as 0 is known as Odd numbers.  2,4,6,8,10....... etc. are example of even numbers.  Whereas 3,5,7,9,11.....etc. are example of odd numbers.&nb ..read more

In mathematics Trigonometry is a branch of mathematics which deals with the relationship between lengths of three sides of a triangle and three angles of a triangle.  We will study about some basic concepts of trigonometry in lower classes of education to make it simple for students easy to understand and pass there mathematics examination.  Let us assume that ∆ABC is a right angled triangle having side AC as hypotenuse and side AB height and side BC as base.  Let us assume that in ∆ABC ∠C= θ Therefore in respect of theta side AB is the opposite side and side BC is ..read more

 In mathematics Pythagoras theorem is discovered by a mathematician named as Pythagoras therefore name is given as Pythagoras theorem.  Without Pythagoras theorem one can not imagine the whole mathematics.  Pythagoras theorem is applicable only in a right angled triangle and is not applicable other than right angled triangle.  Let us assume that ∆ABC is a right angled triangle. In this triangle the side AC is called as "hypotenuse" and side AB and side BC are the other two sides.  Pythagoras theorem states that the square of hypotenuse is equal to addition of sq ..read more

  In mathematics polynomial concept is very important to understand whole mathematics.  The word "POLYNOMIAL" means POLY = MANY and  NOMIAL = TERMS Therefore polynomial is having many terms.  In mathematical language look at the given image and we will give the exact definition of polynomial.  Polynomial can be defined as algebraic expression consist of many terms including variables, coefficients, maths operations such as addition, subtraction etc. and a non negative integer exponent of variable is known as polynomial.  Types of polynomial: A : Monomial polyno ..read more

    PERCENTAGE SYMBOL      In mathematics percentage is a important concept  in mathematics we can not imagine the whole mathematics without percentage. Therefore it is important to understand the concept of percentage.  Percentage word comes from a Latin word Per Centum where the Latin word Centum means 100. Therefore we can define percentage as decimal or fraction of 100. Percentage is denoted by symbol  %. For instance 2% means 2%= 2/100 Which can also be written as 2%= 0.02 in the decimal form.  Let us solve some problems based on percentage ..read more

  In this topic we will discuss about Heron's formula to calculate area of a triangle when height of a triangle is not given but all the three lengths of three sides of a triangle is given then we can easily calculate area of a triangle using Heron's formula.  Heron's formula is discovered by a great mathematician named as Heron Alexandria to calculate area of a triangle therefore the name is given as Heron's formula based on Heron Alexandria name.  When a triangle is given and the lengths of three sides of a triangle is given as a, b and c then By using Heron's formula area of ..read more

 In this topic we will discuss about perimeter of triangle in detail description.  Perimeter of a triangle is denoted by "P". Perimeter can be defined as addition of lengths of three sides of a triangle is known as perimeter of triangle.  Let us assume that a triangle ∆ABC having three sides AB, BC and AC and the length of these three sides is given as AB = c, BC = a and AC = b Therefore perimeter of a triangle is given as P(∆ABC) = AB + BC + AC By putting the values of AB, BC and AC in the above formula we get P(∆ABC) = c+a+b which can be written as P(∆ABC) = a+b+c is the per ..read more

 In this topic we will discuss in detail about area of a triangle. To understand it first we have to understand what is area? can you define area?  Let's define area is the quantity which indicates the extent of two dimensional shape like triangle.  Let's understand about triangle triangle means tri+angle where tri indicates three and angles.  A two dimensional shape having three sides as AB, BC and AC and having three vertex as A, B and C and having three angles is known as triangle.  Let us assume AC= b, AB= c and BC=a and a perpendicular drawn from point B to ..read more

 In this we will discuss in detail about application of pi in mathematics. We can say that pi is a mathematical constant.  How pi is defined? Let's define pi. First we will take circle ⭕ to understand pi concept. You know that circumference of a circle is the total length of circle.  The circumference of a circle is given by a mathematical formula as The notation for circumference of a circle⭕ is denoted by "C". Hence the formula is: C = 2πr where C= circumference of a circle π= mathematical constant and  r = radius of circle We know that D = 2r where D= diameter of circl ..read more

 In mathematics it is very important to understand the concept of directly proportional and inversely proportional.  Let's understand first directly proportional. In the given image of directly proportional you can clearly observe that a linear graph is drawn.  If x and y are two variables then if x is directly proportional to y means if variable x increases then y variable also increases.  We can write it in the mathematical form as x ∝ y means x is directly proportional to y then x =k × y where k is constant means remains same not change.  Therefore x÷y = k The rel ..read more
