The NCERT Class 7 Maths Chapter “Expressions Using Letters and Numbers” introduces students to algebraic expressions using both numbers and variables (letters). Students learn how to form expressions, identify terms, coefficients, and constants, and understand how letters represent unknown quantities in real-life problems. The chapter also explains simplifying expressions and applying basic operations to solve them effectively.
With examples from daily life, this chapter strengthens logical thinking, problem-solving skills, and a foundation for algebra in higher classes. Learners also develop confidence in using letters in mathematical expressions to model and solve practical situations.
