Challenge and Thrill of Pre-College Mathematics is not only a book for students, but also for teachers and parents who want to inspire and motivate their children to learn and enjoy mathematics. The book is written in a clear and engaging style, with many examples, diagrams and illustrations. The book also provides hints and solutions to the problems, as well as references to other books and websites for further reading.

The book is divided into 15 chapters, each covering a different topic of mathematics. The chapters are:

Number Systems: This chapter introduces the concept of number systems, such as natural numbers, integers, rational numbers, irrational numbers and real numbers. It also discusses some properties and operations of these numbers, such as divisibility, prime factorization, fractions, decimals and square roots.

Arithmetic of Integers: This chapter explores some topics related to the arithmetic of integers, such as modular arithmetic, congruences, linear Diophantine equations, Chinese remainder theorem and Fermat's little theorem.

Geometry - Straight Lines and Triangles: This chapter deals with some basic concepts and results of Euclidean geometry, such as angles, parallel lines, triangles, congruence, similarity, Pythagoras theorem and trigonometric ratios.

Geometry - Circles: This chapter focuses on some properties and theorems related to circles, such as tangents, chords, secants, cyclic quadrilaterals, power of a point and radical axis.

Quadratic Equations and Expressions: This chapter explains how to solve quadratic equations and expressions, using various methods such as factorization, completing the square, quadratic formula and Vieta's formulas. It also discusses some applications of quadratic equations and expressions in geometry and number theory.

Trigonometry: This chapter introduces some more topics in trigonometry, such as trigonometric identities, equations and inequalities, inverse trigonometric functions and solutions of triangles.

Polynomials: This chapter studies some aspects of polynomials, such as degree, coefficients, roots, remainder theorem, factor theorem and rational root theorem. It also shows how to find the roots of cubic and quartic polynomials using Cardano's formula and Ferrari's method.

Systems of Linear Equations: This chapter shows how to solve systems of linear equations using various techniques such as elimination method, substitution method, matrix method and Cramer's rule. It also discusses some applications of systems of linear equations in geometry and combinatorics.

Inequalities: This chapter explores some types and properties of inequalities, such as arithmetic mean-geometric mean inequality, Cauchy-Schwarz inequality, Chebyshev's inequality and Jensen's inequality. It also shows how to solve some problems involving inequalities using algebraic manipulation or geometric methods.

Elementary Combinatorics: This chapter introduces some basic concepts and principles of combinatorics, such as counting techniques, permutations and combinations, binomial theorem and Pascal's triangle. It also discusses some applications of combinatorics in probability and number theory.

Beginning of Probability Theory: This chapter explains some fundamentals of probability theory,

such as sample space, events, probability axioms and rules. It also covers some topics such as conditional probability,

Bayes' theorem,

independent events,

mutually exclusive events,

and expected value.

Beginnings of Number Theory: This chapter delves into some topics related to number theory,

such as divisibility,

greatest common divisor,

least common multiple,

Euclidean algorithm,

linear Diophantine equations,

prime numbers,

fundamental theorem of arithmetic,

Euler's phi function,

Euler's theorem,

and Wilson's theorem.

Finite Series: This chapter deals with some types and properties of finite series,

such as arithmetic progression,

geometric progression,

harmonic progression,

arithmetic-geometric progression,

and telescoping series.

It also shows how to find the sum of some special series using induction or other methods.

De Moivre's Theorem and Its Applications: This chapter introduces the concept of complex numbers

and their representation in polar form.

It also explains how to use De Moivre's theorem

to find the roots of complex numbers

and to solve some trigonometric equations.

Miscellaneous Problems: This chapter contains a collection of challenging problems

from various topics covered in the book.

The problems are arranged in increasing order of difficulty
