The Caribbean Teacher's Series (CTS) content is created by teachers who teach in our schools in the Caribbean everyday. Only by teaching over many years can one understand the difficulties faced by our students. The CTS series aims to capture and present this knowledge and experience from many teachers across many schools, with a video solution for every question, that is recorded by the teacher who wrote the question. A student using this book together with the CTS Maths App will have the unique virtual learning experience of meeting the teachers from different schools, using their notes and sitting next to the teachers as they solve the questions in this book. The topics covered are Number Theory, Computation, Consumer Arithmetic, Algebra, Sets, Measurements, Graphs, Relations and Functions, Geometry and Trigonometry, Statistics, Vectors and Matrices, for students in the Caribbean undertaking the final examination at the secondary school level in Mathematics.
