Basic mathematics formula


What are the basic Maths formulas?

The basic Maths formulas include arithmetic operations, where we learn to add, subtract, multiply and divide. Also, algebraic identities help to solve equations. Some of the formulas are:

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

(a – b)2 = a2 + b2 – 2ab

a2 – b2 = (a + b) (a – b)

What are the fundamental topics for formulas in Maths?

The fundamental concepts we learn for maths formulas are:

Area and perimeter of shapes

Surface areas and Volumes

Algebra

Powers and exponents

Fractions

Percentage, etc.

What are the important Maths formulas?

The important formulas are related to algebra, Pythagoras theorem, series and sequence, mensuration, calculus, probability and statistics, trigonometry, matrices, etc.

What are the area and perimeter formulas?

The area of a shape defines the region covered by it whereas the perimeter gives the total length of the outer boundary of the shape. The area is measured in square units but the perimeter is denoted by the unit of the dimension. Suppose, the formula for the area of a square is side2 sq. units. and perimeter of a square is 4(side) units.

What is a3 – b3 formula?

The formula for a3 – b3 is given by:

a3 – b3 = (a – b) (a2 + ab + b2 )
