List of Maths formulas

Maths formulas and Maths formulas sheets are the most usefully content for all most every student. We have created a detailed Maths sheet of all important formulas used while solving Maths problems. Our academic team consist of more than six thousand maths teachers who are involved in Home tuitions across the county having experience in teaching students of different boards like CBSE, ICSE, state board and different competitive entrance exams like JEE, NTSE, SSC, and UPSC. Such experienced teachers understand the role and use of Maths formulas and know-how to prepare the Maths formulas sheet. Based on our teacher's vast experience we have selected the most used Maths formulas and prepared a list of Maths formulas to help students in final revisions.

Key features of Maths formulas

We have prepared one sheet for each Maths formula having the following key features

  1. All maths formulas are convers in the following sheet starting from class 1 Maths formulas to graduation level Maths formulas.
  2. For each math formula, we have prepared a different sheet and page to give you all details required.
  3. Each Maths formulas sheet not only covers the formula details but also added all the details required to understand the application of the formulas in the numerical.
  4. All formulas are explained with the help of solved examples so that students can not only learn the important formulas but also understand the application of formulas through the use of solved examples
  5. Few Maths formulas required a bit more explanation, for such formulas we have added proper theory and images to explain such concepts.

Frequently Asked Questions on Maths formulas

The basic Maths formulas are used in all most all classes while solving any numerical or maths questions you need to understand the application of basics maths formulas generally these formulas are from a few chapters and used in all most all chapters not only in maths but also in other subjects on which basics maths is required, few chapters having basics maths formulas use are basics of algebra, mensuration, tribometer arithmetic operations, basics Geometry in higher Maths you must learn calculus formulas. A few basics Maths formulas used in every chapter are. 

(a+b)2 = a2 + b2 + 2ab

(a-b)2 = a2 + b2 - 2ab

(a+b)(a-b) = a2-b2

(x + a)(x + b) = x2 + (a + b)x + ab

(x + a)(x-b) = x2 + (a-b)x-ab

(a + b)3 = a3 + b3 + 3ab

(a + b) (a-b)3 = a3-b3-3ab(a-b)

(x-a)(x + b) = x2 + (b-a)x-ab.

Basic formulas of Maths include all the formulas which are being used in calculation of all most chapters of maths like algebra, integers and use of bodamas. We have added all basics maths formulas in this page. Check out the above sheet it includes basic maths formulas class wise. 

There is no specific top 10 formulas used in Maths, but a few formulas are used frequently while solving the questions in every class generally, such formulas are form Algebra And Quadratic Equation Formulas. Based on which class you are in maths formulas are selected, we have carefully selected the top 10 Maths formulas class-wise for your better learning just check it out the above page and find your class and learn top 10 maths formulas accordingly. 

There are lots of Maths formulas which are used frequently while solving maths questions, just like physics Albert Einstein E=mc2 there is no such maths formulas is famous but still if anyone you wants to ask maths formulas all most all people ask what is (a+b)2. We use this formula so frequently that we can say this is most famous Maths formulas. 

To simplify your search on Maths formulas we have created this page. This page consists of all most all Maths formulas lists and details. Check out the list given above and download your maths formulas.

The best way to use Maths formulas starts with understanding the concepts used in the chapters. Always start with understanding the syllabus of Maths and then select one chapter read the theory given in the chapter, and make sure you are preparing the proper notes and writing all the formulas used in the chapters. Once you understood the chapter start solving the numerical. Solving numerical is the best way to have a solid foundation in Maths subjects. Once you are in the stage of solving questions of maths you will find it fun and your speed of solving the numerical are depends on how fast you remember the basic maths formulas and their applications. Numerical solving skill enterally depends on your skill and concepts and its speed depends on how you have practised the Maths formulas. In short, students must remember that memorising only maths formulas won’t help you before start memorising the formulas you must have a very clear concept in the chapter.
