Basic Math Formulas

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 = a2

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 × (b1 + b2) × h

Where b1 and b2 are the bases of the Trapezoid; h = height of the Trapezoid

  • Area of Circle = A = π × r2

  • Circumference of Circle = A = 2πr

Where ‘r’ is the radius of a Circle

  • Surface Area of Cube = S = 6a2

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 = πr2h

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 + √(h2 + r2)]

  • Volume of a Cone = V = ⅓ × πr2h

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

  • Surface Area of a Sphere = S = 4πr2

  • Volume of a Sphere = V = 4/3 × πr

Where, r = Radius of the Sphere

Basic Probability Formula

P(A) = n(A)/n(S)


  • P(A) is the probability of an event “A”.

  • n(A) is the number of favorable outcomes.

  • n(S) is the total number of events in sample space.

Basic Arithmetic Formulas

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

FAQs (Frequently Asked Questions)

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:

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

  2. It improves the score in Board Exams and Entrance Examinations.

  3. It makes complete Preparation easy on time.
