第三版透過「螺旋」方法全面涵蓋了核心和擴展內容，學生在學習課程的過程中以先前的學習為基礎。除了大量的練習題和對英語作為第二語言學習者的支持之外，我們還納入了NRICH 提供的許多項目，鼓勵學生將理論付諸實踐——NRICH 是大學數學學院和教育學院之間的合作計畫劍橋的。
The third edition fully covers both Core and Extended content through the 'spiral' approach, where students build on their previous learning as they progress through the course. In addition to a wealth of practice questions and support for English as a second language learners, we have included a number of projects to encourage students to put their theory into practice provided by NRICH – a collaboration between the Faculties of Mathematics and Education at the University of Cambridge. Answers are available on Cambridge GO.
