Number Theory
Master CSEC number theory — the sets of real numbers and their inclusion relations, ordering reals, even/odd/prime/composite and square numbers, number patterns and sequences (generating terms and deriving rules), factors and multiples with HCF and LCM, place and face value in base n, and the properties of numbers and operations. Each lesson has worked examples and practice.
