Structure And Calculation
Bayani Gaba-gaba
Every other topic in this course is standing on this one. Solve a quadratic and you are factorising; find the area of a circle and you are rounding; work with a bearing and you are reading a calculator display correctly. The eleven specification references gathered here, N1 to N11, are the machinery the rest of the subject runs on, and a candidate who is shaky on any of them will lose marks in questions that look nothing like arithmetic.
You will order numbers and use the six comparison symbols precisely; apply the four operations to negatives, decimals and mixed numbers; break a number into its prime factors and use that to find a highest common factor in seconds; handle powers, roots and index laws; write and read standard form; use set notation and Venn diagrams; round sensibly and estimate quickly; and, on the Extension Tier, work exactly with surds, rationalise a denominator and calculate with upper and lower bounds. The single most profitable habit in this topic is refusing to round until the very last line.
Manufura
- [Core] order positive and negative integers, decimals and fractions
- [Core] use the symbols =, ≠, <, >, ≤, ≥ (Notes: including use of a number line)
- [Core] 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
- [Core] understand and use place value (eg when working with very large or very small numbers, and when calculating with decimals) (Notes: including questions set in context)
- [Core] recognise and use relationships between operations, including inverse operations (eg cancellation to simplify calculations and expressions)
- [Core] use conventional notation for priority of operations, including brackets, powers, roots and reciprocals
- [Core] use the concepts and vocabulary of even, odd and prime numbers, factors (divisors), multiples, common factors, common multiples, highest common factor, lowest common multiple, prime factorisation, including using product notation (Notes: prime factor decomposition including product of prime factor written in index form)
- [Core] use positive integer powers and associated real roots (square, cube and higher), recognise powers of 2, 3, 4, 5
- [Core] index laws for multiplication and division using integer powers
- [Extension] including fractional powers
- [Core] calculate exactly with fractions
- [Extension] calculate exactly with surds
- [Extension] manipulation and simplification of surds including rationalising a denominator
- [Core] calculate with and interpret standard form A × 10ⁿ, where 1 ≤ A < 10 and n is an integer (Notes: interpret calculator displays)
- [Core] use language and notation of sets including n(A), A′, A ∩ B, A ∪ B, ξ
- [Core] understand and use Venn diagrams to solve problems
- [Core] use calculators effectively and efficiently including trigonometrical functions
- [Core] round numbers and measures to an appropriate degree of accuracy (eg to a specified number of decimal places or significant figures)
- [Core] apply and interpret limits of accuracy
- [Core] use estimation to work out approximate answers to calculations
- [Extension] calculate and use upper and lower bounds
