# What is Mathematics?

Mathematics is one of the most important subjects. It is a subject of numbers, shapes, data, measurements, and also logical activities. It has a huge scope in every field of our life, such as medicine, engineering, finance, natural science, economics, etc. We are all surrounded by a mathematical world.
The concepts, theories, and formulas that we learn in Maths books have huge applications in real-life. To find the solutions for various problems we need to learn the formulas and concepts. Therefore, it is important to learn this subject to understand its various applications and significance.

Basic Mathes

The fundamentals of maths begin with arithmetic operations such as addition, subtraction, multiplication, and division. These are the basics that every student learns in elementary school. Here is a brief of these operations.

• Addition: Sum of numbers (Eg. 1 + 2 = 3)
• Subtraction: Difference between two or more numbers (Eg. 5 – 4 = 1)
• Multiplication: Product of two or more numbers (Eg. 3 x 9 = 27)
• Division: Dividing a number into equal parts (Eg. 10 ÷ 2 = 5, 10 is divided into 2 equal parts) #### Branches of Mathematics

The main branches of mathematics are:

• Number System
• Algebra
• Geometry
• Calculus
• Topology
• Trigonometry
• Probability and Statistics

These mathematical concepts fall under pure mathematics. These form the base of mathematics. In our academics, we will come across all these theories and fundamentals to solve questions based on them.

Applied mathematics is another form, where mathematicians, scientists, or technicians use mathematical concepts to solve practical problems. It describes the professional use of mathematics.
