Numbers expressed using figures -- 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0 are called digits. Out of these, 0 is called the ‘in significant’ digit whereas the others are called significant digits.
Numerals: A group of figures, representing a number, is called a numeral. Numbers are divided into the following types:
Natural Numbers
Numbers are used for counting the object. Natural numbers are represented by N
N = {1, 2, 3, 4, 5, ….}
Whole Numbers
When we include zero in the natural numbers, it is known as whole numbers. Whole numbers are denoted by W.
W = {0, 1, 2, 3, 4…….}
Prime Numbers
A number other than 1 is called a prime number if it is divisible only by 1 and itself.
Composite Numbers
A number, other than 1 which is not a prime number is called a composite number.
e.g. 4, 6, 8, 9, 10, 12, …etc.
Even Numbers
The number which is divisible by 2 is known as an even number.
e.g . 2, 4, 6, 8, 10, …. etc.
It is in the form 2n (where n is a whole number)
Odd Numbers
A number that is not divisible by 2 is known as an odd number.
e.g. 3, 9, 11, 17, 19, … etc.
Consecutive Numbers
A series of numbers in which each is greater than its predecessor by 1, is called consecutive numbers.
e.g. 6, 7, 8, or 13, 14, 15 or 101, 102, 103.
Integers
The set of numbers that consists of whole numbers and negative numbers is known as integers. It is denoted by me.
e.g. I = {-4, -3,-2, -1, 0, 1, 2, 3, 4}
Rational numbers
When the numbers are written in fractions, they are known as rational numbers. They are denoted by Q. e.g. rational numbers. Or, the numbers which can be written in the form a/b (where a and b are integers and b is not equal to 0) are called rational numbers.
Irrational Numbers
The numbers which cannot be written in form of p/q are known as irrational numbers (where p and q are integers and q not equal to 0).
Real Numbers
Real numbers include both rational as well as irrational numbers.

Geometry is another high-volume Maths topic that plays a vital role in both academics and practical life. It deals with points, lines, angles, shapes, and their properties. Students study theorems, constructions, and proofs which improve logical thinking and reasoning. Geometry is important because it develops visualization skills and helps students understand the world around them—from the design of buildings to patterns in nature. In school-level exams, topics like triangles, circles, quadrilaterals, and coordinate geometry are considered scoring. Competitive exams also test knowledge of Geometry through theorems and problem-solving. Beyond academics, Geometry has applications in architecture, computer graphics, engineering, and robotics. A student who practices Geometry regularly not only secures good marks but also enhances spatial awareness. For effective preparation, it is important to remember theorems, practice diagrams, and solve a variety of examples. Geometry strengthens the foundation of Mathematics and links directly to advanced topics like Trigonometry and Calculus.
Statistics and Probability are Maths topics that have gained tremendous importance in modern education. Statistics deals with collecting, organizing, and interpreting data, while Probability measures the chance of events happening. Students often search for these topics because they are directly linked to real-world applications. Statistics helps in fields like economics, research, sports analysis, and business forecasting. For example, calculating averages, percentages, and trends are common uses of statistics. Probability is applied in predicting weather, playing games of chance, and risk management. In academics, Statistics and Probability are important for both board exams and competitive exams, especially for students opting for commerce, economics, and data science careers. Learning mean, median, mode, standard deviation, and probability formulas step-by-step makes the subject easier. By practicing solved examples and applying these concepts in real life, students can see the practical side of Mathematics. These topics not only improve exam performance but also prepare learners for real-world problem solving.
Formulas are the backbone of Mathematics, and students frequently search for important Maths formulas before exams. The key formulas vary depending on the class and syllabus but usually include Algebra formulas (like expansion of identities and quadratic equations), Geometry formulas (area and perimeter of figures), Trigonometry formulas (sine, cosine, and tangent identities), Calculus formulas (derivatives and integrals), and Statistics formulas (mean, variance, and probability rules). Learning formulas systematically allows students to save time during exams and ensures accuracy. A formula chart or notebook can be very helpful for quick revisions. To effectively memorize formulas, students should practice them through solved examples and apply them in real problems. Many exam questions are directly based on formulas, making them scoring topics. Hence, learning and revising formulas regularly is one of the best ways to strengthen preparation for both school exams and competitive exams like JEE, NEET, and Olympiads.
Preparing all major Maths topics like Algebra, Geometry, Trigonometry, Calculus, Statistics, and Probability requires a structured approach. The first step is to understand basic definitions and theorems before moving on to problem-solving. Students should maintain a Maths formula sheet for quick revision and solve NCERT exercises along with exemplar problems. Regular practice of past-year question papers helps in identifying exam patterns. Another effective strategy is to apply concepts to real-life examples—for instance, using percentages in shopping, probability in games, or Geometry in construction. Time management is also important; students should dedicate equal time to both strong and weak topics. Online resources and step-by-step solutions are useful for clearing doubts. Most importantly, consistency in practice builds speed and accuracy, which are vital during exams. By following these strategies, students can cover all major Maths topics with confidence and improve their overall performance in board and competitive exams.
