A rule written with symbols that connects two or more quantities.
Used by AQA, Edexcel and OCR
Specification A2, A3, A5, A21 · Paper 1, Paper 2, Paper 3
An equation that gives a rule connecting two or more quantities, such as .
Revise: SubstitutionAn unfamiliar formula will be provided in the question, although some standard formulae are prescribed elsewhere in the course.
Classify a statement by its mathematical role, not just by the letters it contains: a formula is also an equation, but it specifically expresses a relationship between variables.
Use for an equation or formula. Use when explicitly stating that two expressions are identical for every permissible value of their variables.

Specification 6.01a, 6.02a, 6.02b · Paper 1 (Foundation), Paper 2 (Foundation), Paper 3 (Foundation), Paper 4 (Higher), Paper 5 (Higher), Paper 6 (Higher)
An equation that gives a rule connecting quantities, often allowing one quantity to be calculated from others.
Revise: Algebraic Proofs and TermsA formula is an equation used as a rule connecting quantities.
A rule written with symbols that shows how one quantity is calculated from other quantities; for example, .
A mathematical statement giving a relationship between quantities, usually containing an equals sign.
Do not assume that every formula will be printed in the examination: AQA identifies some formulae that students are expected to know or derive, subject to the relevant tier.
