## Concept of the Basic Mathematics Formulas

The basic mathematics formula is generally used in basic maths and which are not only used in academic books but also in our daily lives. In the primary class, we all have learned about the general BODMAS rule. As one keeps on approaching the higher classes from six to ten one will come across the various mathematics formula based on various concepts such as algebra.

By practicing the questions and answers based on various formulas one can by heart each and every formula before appearing for the exams.

Some of the other concepts which have formulas are given below:

Fractions

Percentage

Formula for proportion

Geometry

Trigonometric formulas and many more.

### Basic Mathematics Formula

The basics of math display how a math problem can be solved with the help of some equations like the equation of forces, accelerations, or the work done. More importantly, they are used to provide mathematical solutions for real-world problems in our day-to-day life.

There are many types of equations, and they are found in many areas of maths. But the techniques used to examine them differ according to their type. It can be as simple as the basic addition formula or can be complicated as integration of differentiation.

### Basic Geometry Formulas

The perimeter of Square = P = 4a

Where ‘a’ is the length of the sides of square

Perimeter of Rectangle = P = 2(l + b)

Where ‘l’ is Length and ‘b’ is Breadth

The area of Square = A = a

^{2}

Where ‘a’ is the length of the sides of a Square

The area of Rectangle = A = l × b

here ‘l’ is Length and ‘b’ is breadth

Area of Triangle = A = ½ × b × h

Where ‘b’ is the base of the triangle and ‘h’ is the height of the triangle

Area of Trapezoid = A = ½ × (b

_{1}+ b_{2}) × h

Where b_{1} and b_{2} are the bases of the Trapezoid; h = height of the Trapezoid

Area of Circle = A = π × r

^{2}Circumference of Circle = A = 2πr

Where ‘r’ is the radius of a Circle

Surface Area of Cube = S = 6a

^{2}

Where ‘a’ is the length of the sides of the Cube

The curved surface area of Cylinder = 2πrh

The total surface area of Cylinder = 2πr(r + h)

The volume of Cylinder = V = πr

^{2}h

Where ‘r’ is the radius of the base of Cylinder and ‘h’ is height of Cylinder

The curved surface area of a cone = πrl

Total surface area of cone = πr(r + l) = πr[r + √(h

^{2}+ r^{2})]Volume of a Cone = V = ⅓ × πr

^{2}h

Here, ‘r’ is the radius of the base of Cone and h = Height of the Cone

Surface Area of a Sphere = S = 4πr

^{2}Volume of a Sphere = V = 4/3 × πr

Where, r = Radius of the Sphere

## Basic Probability Formula

### Basic Arithmetic Formulas

Arithmetic mean (average) = Sum of values/Number of values.

Q1. What is a Formula?

Ans. A formula is a fact or the rule that is written with all the mathematical symbols. It usually connects two or more than two quantities with an equal sign. When one knows the value of one quantity the one can also find the value of the other using the formula respectively.

Q2. Give Examples of Some Basic Math Formulas.

Ans. Some examples of the basic math formulas:

Perimeter of a rectangle = 2 (length + width)

Area of rectangle = length × width

The perimeter of a square = 4 × side length

Area of square =Side length × side length

The volume of cuboid = length × width × height

Profit = Selling price - cost price

Loss = Cost price - selling price

Q3. What is the Importance of Learning Basic Math Formulas?

Ans. Following are the reasons for which we need to know and learn the basic maths formulas:

Basic Maths formulas help all the students to complete the syllabus in a unique do-learn-do pattern of study.

It improves the score in Board Exams and Entrance Examinations.

It makes complete Preparation easy on time.
