LSC1: WORKING WITH INTEGERS

This unit is about calculations with positive and negative integers, identifying reading and writing natural numbers as numerals and words in million, billion, and trillion (u, s), differentiating between natural numbers and whole numbers/integers (u), identifying directed numbers (k), using directed numbers (limited to integers) in real-life situations (u,s), using the hierarchy of operations to carry out the four mathematical operations on integers (u), identifying even, odd, prime and composite numbers (k, u), finding the prime factorization of any number (k, u, s), relating common factors with HCF and multiples with LCM (k, u, s, v) and working out and use divisibility tests of some numbers. (k, u, s, v/a).
