## CSEC NUMBER THEORY

At the end of this course, students should be able to:

- distinguish among sets of numbers;
- identify a set of numbers as a subset of another set;
- order a set of numbers;
- generate the term of a sequence;
- given a rule derive an appropriate rule given the terms of a sequence;
- compute the H.C.F or L.C.M of two or more positive integers;
- state the value of a digit in a numeral in base , where ;
- use properties of numbers and operations in computational tasks;

## Your Instructor

Sean Hunte, Your Passionate Mathematics Teacher

I was once a student just like you. I struggled with Mathematics for the first two (2) years of my secondary school life. In third form my teacher, Dr Sargeant, taught Mathematics in a unique way which allowed me to successfully learn the subject which I was passionate about. Her teaching enabled me to thrive in an area which I would eventually pursue as a career.

Therefore, I have successfully completed CXC's CSEC General Mathematics and CAPE Pure Mathematics Units 1 and 2 before obtaining a degree in Economics and Mathematics.

I have ten (10) years of experience teaching Mathematics at the secondary level in Barbados. During this time I have taught hundreds of students who have successfully completed the following courses:

- CSEC GENERAL MATHEMATICS
- CSEC ADDITIONAL MATHEMATICS
- CAPE PURE MATHEMATICS UNIT 1
- CAPE PURE MATHEMATICS UNIT 2
- SAT MATHEMATICS

Your story will be different from mine but both of us desire the same result. SUCCESS!

I know that for many students Mathematics can be a struggle. I am therefore here to offer assistance in making the learning of Mathematics easier.
