-====== Structure and Calculation ======
-===== Specification =====
-**N1**
-order positive and negative integers, decimals and fractions; use the symbols =, ≠, <, >, ≤, ≥
-==== Types of Number ====
-**N2**
-apply the four operations, including formal written methods, to integers, decimals and simple fractions (proper and improper), and mixed numbers – all both positive and negative; understand and use place value (e.g. when working with very large or very small numbers, and when calculating with decimals)
-**N3**
-recognise and use relationships between operations, including inverse operations (e.g. cancellation to simplify calculations and expressions); use conventional notation for priority of operations, including brackets, powers, roots and reciprocals
-**N4**
-use the concepts and vocabulary of prime numbers, factors (divisors), multiples, common factors, common multiples, highest common factor, lowest common multiple, prime factorisation, including using product notation and the unique factorisation theorem
-**N5**
-apply systematic listing strategies, including use of the product rule for counting (i.e. if there are m ways of doing one task and for each of these, there are n ways of doing another task, then the total number of ways the two tasks can be done is m × n ways)
-**N6**
-use positive integer powers and associated real roots (square, cube and higher), recognise powers of 2, 3, 4, 5; estimate powers and roots of any given positive number
-**N7**
-calculate with roots, and with integer and fractional indices
-**N8**
-calculate exactly with fractions, surds and multiples of π; simplify surd expressions involving squares (e.g. √12 = √(4 × 3) = √4 × √3 = 2√3) and rationalise denominators
-**N9**
-calculate with and interpret standard form A × 10n, where 1 ≤ A < 10 and n is an integer
