數學：核心主題 HL 是為 IB 文憑課程數學：分析與方法 HL 和數學：應用與解釋 HL 編寫的，將於 2019 年 8 月首次教學，並於 2021 年 5 月首次評估。
本書包含兩門課程共有的內容。這些材料都可以先教授，這樣就有可能在課程開始時一起教授所有 HL 學生。
這是學生完成 HL 數學課程所需的兩本書中的第一本。讀完本書後，學生將繼續學習其課程的特定 HL 教科書：數學：分析和方法 HL 或數學：應用和解釋 HL。
Mathematics: Core Topics HL has been written for the IB Diploma Programme courses Mathematics: Analysis and Approaches HL, and Mathematics: Applications and Interpretation HL, for first teaching in August 2019, and first assessment in May 2021.
The book contains the content that is common to both courses. This material can all be taught first, giving the potential to teach all the HL students together from this book at the start of the course.
This is the first of two books students will require for the completion of their HL Mathematics course. Upon the completion of this book, students progress to the particular HL textbook for their course: either Mathematics: Analysis and Approaches HL, or Mathematics: Applications and Interpretation HL. This is expected to occur approximately 6-7 months into the two-year course.
