CBSE Class 7 Mathematics deepens algebra and introduces rational numbers. Students work with integers across all four operations, rational numbers, exponents and powers, and algebraic expressions including addition, subtraction and simple equations.

Geometry covers lines and angles, triangles and their properties, congruence, and practical geometry constructions. Comparing quantities introduces percentage, profit and loss and simple interest, and data handling covers mean, median, mode and probability.

Key topics covered

• Integers & Rational Numbers — All four operations with integers and rational numbers.
• Exponents & Powers — Laws of exponents and expressing large numbers in standard form.
• Algebraic Expressions — Terms, coefficients, and adding, subtracting and evaluating expressions.
• Simple Equations — Forming and solving linear equations from word problems.
• Comparing Quantities — Percentage, ratio, profit and loss, and simple interest.
• Geometry — Lines and angles, triangle properties, congruence and constructions.
• Perimeter, Area & Data — Area of triangles and parallelograms, and mean, median, mode and probability.
