Requirement: All students at Xavier College Preparatory must complete six consecutive semesters of mathematics beginning with Algebra I or above and through Algebra II, although eight semesters are recommended.
The Math Department’s goal is for students to develop the necessary perseverance to work through challenging problems using critical thinking while taking personal responsibility for their individual learning. In addition to competency in math fundamentals, classes encourage an appreciation for the study of math and its applications in the real world. Our math program is rigorous but flexible, serving the needs of students of all abilities. Students from any freshman math class are given the opportunity to accelerate eventually into any Advanced Placement course within the Math Department. The curriculum is designed to give students a solid foundation in math so that they may find sustained success across all disciplines as well as college-level math.

ADVANCED COURSES
Prerequisite: Successful completion of Algebra II/Trigonometry or Pre-AP Algebra II.
Advanced Algebra with Financial Applications is a mathematical modeling course that is algebra-based, applications-oriented, and technology-dependent. The course addresses college preparatory mathematics topics from Advanced Algebra, Statistics, Probability, Precalculus, and Calculus under seven financial umbrellas: Banking, Investing, Credit, Employment, Income Taxes, Automobile Ownership, Independent Living, Retirement Planning, and Household Budgeting. The course allows students to experience the interrelatedness of mathematical topics, find patterns, make conjectures, and extrapolate from known situations to unknown situations. The mathematics topics contained in this course are introduced, developed, and applied in an as-needed format in the financial settings covered. Students are encouraged to use a variety of problem-solving skills and strategies in real-world contexts and to question outcomes using mathematical analysis and data to support their findings. The course offers students multiple opportunities to use, construct, question, model, and interpret financial situations through symbolic algebraic representations, graphical representations, geometric representations, and verbal representations. The use and development of critical thinking skills is crucial in this course.
Prerequisite: Successful completion of Algebra II/Trigonometry or Pre-AP Algebra II.
With the recent advent of massively powerful computers and artificial intelligence, game theory departed from the world of abstract concepts (pioneered by John von Neumann and John Nash) and entered into the world of practical realities. Today, for any “zero-sum” game, we can study computed solutions for the “Game Theory Optimal” strategy against which no player can win, but only stalemate. Using that knowledge as a foundation, players can learn how to maximally exploit weaknesses in imperfect strategies, thus discovering the mathematical limit of victory against any given opponent. Modeled after similar courses offered at UC Berkeley, MIT, and other universities, this course uses the game of Texas Hold’Em Poker as a framework for understanding these concepts. Making use of cutting-edge AI technology released to the public only this year, this course will use “GTO ‘Game Theory Optimal’ Wizard” node locking to compute solutions for study. By applying and mastering game-theoretical concepts for this specific game, students will learn how to see the world through a game-theoretical lens and apply their skills to a breadth of other fields such as economics, politics, social science, and more. (Note that this course treats poker academically and has no relationship with nor advocacy for gambling of any kind.)
Prerequisite: Successful completion of Algebra II/Trigonometry or Pre-AP Algebra II.
Precalculus is a survey course in advanced mathematical concepts, designed for high school seniors. It is intended for those who do not qualify for Honors Pre-Calculus. The emphasis is on reinforcing algebraic techniques, functions, and logarithms, while also introducing trigonometry, sequences and series, probability, statistics, matrices, and vectors.
Prerequisite: Successful completion of Algebra II/Trigonometry or Pre-AP Algebra II.
AP Precalculus serves as a rigorous prelude to AP Calculus AB. The course framework includes two essential components:
MATHEMATICAL PRACTICES
The mathematical practices are central to the study and practice of precalculus. Students should develop and apply the described skills on a regular basis over the span of the course.
AP Precalculus focuses on three main practices:
Practice 1: Procedural and Symbolic Fluency
Practice 2: Multiple Representations
Practice 3: Communication and Reasoning
COURSE CONTENT
The course content is organized into units of study that provide a suggested sequence for the course. These units comprise the content and conceptual understandings that colleges and universities typically expect students to master to qualify for college credit and/or placement.
AP Precalculus has four main units:
Unit 1: Polynomial and Rational Functions
Unit 2: Exponential and Logarithmic Functions
Unit 3: Trigonometric and Polar Functions
Additional Topics Available to Schools (Not Included on AP Precalculus Exam)
