Most maths books show you the answer. This one asks you to work it out first.

PP NextGen Maths for Middle School, Book 1: Number System & Algebra contains 1,000 numbered questions in order. Part I covers the number system in questions 1 to 500, from divisibility and fractions to powers, roots and number properties. Part II covers algebra in questions 501 to 1,000, including expressions, equations, patterns and sequences.

Every question is graded from foundation (D1) to expert challenge (D6), so you can choose work that matches your confidence. Each one includes a complete worked solution, a common trap that catches students who rush, an alternate method to check your result, and an extension question with its answer shown.

Written for students in classes 6 to 8, and useful for olympiad and JEE-style problem-solving practice, this book rewards slow, careful work. Attempt each question before reading the solution, and you will find that the patterns in numbers and expressions begin to make sense on their own.
