Mathematics is the subject which is being studied since the beginning of time. Because almost every principle in this universe can be explained using mathematics, it has turned into a vast subject consisting of various formulas and equations which can help you solve problems seen in practical life. These mathematical concepts are taught to us in every grade and our level of understanding also increases gradually. Some of the concepts are given below.

Equal To & Equations

We have seen the equal to sign (=) in maths all the time and we should know that it has a greater significance. An equal to sign in the middle of a maths statement is named as an equation. Equations are part of every expression in mathematics


The number line represents all sorts of numbers whether it would be a real number. The fractions can be represented in preceding order between 0 and 1 and rational numbers and irrational numbers are also part of this line.

Functions & Graphs

The reason behind the usage of the graph is for bringing a clear and graphical representation of data in geometry and algebra which enables you to draw solutions to equations which can include geometric shapes, the variables, point etc. Functions, on the other hand, is a mechanism by which you will be inserting one value and you will get another value in return depending on the nature of the function.

Pi & Zero

Pi which is the ratio of the circumference of a circle to the diameter was a very important invention along with zero. Zero is used to represent where the value is nothing or null and the basic usage of Pi is in trigonometry.

Use of Sets

To define numbers and operations such as subtraction and addition, sets are used. Generally, sets are used to cluster and organize some data and which indeed will be easy to solve systematically.


The study of figures in a plane or space is called as geometry and every geometrical figure occupies some area whether it would be the area of rectangle or circle or square. Knowing how to find area will be useful in the calculation of complex data.
