Unit I · Number Systems The HCF × LCM relation is for two numbers. It does not hold for three. Unit II · Algebra Unit II · Algebra Solve by substitution or elimination. Check the answer in both equations. Unit II · Algebra Unit II · Algebra a is the first term, d the common difference, n the number of terms. Unit III · Coordinate Geometry Unit IV · Geometry These are results, not formulas. CBSE asks you to prove the first and the last two, and to state the rest. Unit V · Trigonometry Unit V · Trigonometry Draw and label the figure first. Problems use not more than two right triangles. Unit VI · Mensuration Take π = 22/7 unless the question says otherwise. For segments, CBSE restricts the central angle to 60°, 90° and 120°. Unit VI · Mensuration Combined solids: add the volumes. For surface area, add only the surfaces you can see. TSA is total surface area, CSA is curved (or lateral) surface area. Unit VII · Statistics and Probability Median: l is the lower limit of the median class, n the total frequency, cf the cumulative frequency before it, f its frequency, h the class size. Mode: l is the lower limit of the modal class, f 1 its frequency, f 0 and f 2 the frequencies of the classes before and after it. Unit VII · Statistics and Probability This is for equally likely outcomes. Two dice have 36 outcomes. A pack of cards has 52. Short answer. Class 10 Maths has 7 units and 15 chapter headings. The formulas you will use most are the quadratic formula, the nth term and sum of an AP, the distance and section formulas, the trigonometric identities, and the surface area and volume formulas. All are above. Source : CBSE Curriculum 2026-27, Class X Mathematics (Subject Code 041 & 241) , pp.3-7 The sheet includes only topics named in the CBSE 2026-27 curriculum.
