Class 8 Mathematics — Algebraic Expressions and Identities Important Questions with Answers (Short answers)

Class 8 Mathematics is the last middle-school year before Class 9 polynomials and Euclid. Rational numbers get a full number-line treatment, linear equations move beyond one-step, and mensuration adds cubes and cylinders. This bank follows the rationalized NCERT so you are not revising deleted chapters. Search terms such as “class 8 rational numbers important questions” and “linear equations class 8 MCQ” open the matching chip. Twenty questions a page, answers folded.

Algebraic Expressions and Identities — बीजीय व्यंजक और सर्वसमिकाएँ

(a+b)², (a−b)², (a+b)(a−b) and (x+a)(x+b) are the four identities Class 8 actually uses. Expansion and factorisation are two directions of the same street. Degree and like terms still govern addition. Numericals such as 102² via (100+2)² are the speed items. You are on Algebraic Expressions and Identities (Short answers), page 1 of 1 — 3 questions in this filter. Short answers are two-to-four line NCERT points — definition, reason, or a small numerical. Write in the language your school paper uses (Hindi or English) then match the hidden paragraph. These are the 2- and 3-mark stems teachers recycle. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL. Updated for 2026 classroom practice on the rationalized NCERT.
