Number Play

Numbers love games: reversing digits, testing divisibility and hunting for missing digits in puzzles. This topic in the Class 8 mathematics syllabus collects such play into the study of number patterns and divisibility rules. You will test numbers for divisibility by small divisors, explain why the tests work using place value, generalise two- and three-digit numbers in algebraic form, and crack puzzles about ages and digit reversals. The play sharpens mental arithmetic while revealing the structure hidden inside ordinary numbers.
