Tap to flip Answer Notations or processes that are generally agreed upon Question By convention, how is a multiplied by 3 written? Tap to flip Answer 3a (not a3) Question What is an identity? Tap to flip Answer An equation that holds true for all values of the variables Question Which symbol shows that two expressions form an identity? Tap to flip Answer ≡ Question What is a formula? Tap to flip Answer A rule linking sets of physical variables in context Question What is the plural of formula? Tap to flip Answer Formulae Question What is a numerical coefficient? Tap to flip Answer A constant multiplier of the variables in a term Question What is a constant? Tap to flip Answer A term that does not change; it contains no variables Question What is the coefficient of b in a - 2b? Tap to flip Answer -2 Question In algebra, what is substitution used for? Tap to flip Answer Replacing variables with values Question What are like terms? Tap to flip Answer Terms with the same set of variables and corresponding exponents Question Are 2y and 3y like terms? Tap to flip Answer Yes: different coefficients do not stop them being like terms Question What does unitising mean? Tap to flip Answer Treating groups that contain the same numbers of things as 'ones' or 'units' Question What does it mean to simplify an expression? Tap to flip Answer Write it in the most efficient, compact form without changing its value Question When is an expression fully simplified? Tap to flip Answer When it cannot be simplified any further Question Does 3(y + 2) expand to 3y + 2? Tap to flip Answer No: the 3 multiplies both y and 2 Question Which law helps you multiply an expression by a constant? Tap to flip Answer The distributive law Question What is a^2 × a written as a product of a's? Tap to flip Answer a × a × a Question Is 5(y + 1) - 2(y + 3) equal to 5y + 5 - 2y + 6? Tap to flip Answer No Question Can an expression sometimes be simplified before multiplying out? Tap to flip Answer Yes Question In algebra, what is a factor? Tap to flip Answer A term which exactly divides another term Question What are the factors of 7ab? Tap to flip Answer 1, 7, a, b, 7a, 7b and ab Question What does it mean to factorise? Tap to flip Answer To express a term as the product of its factors Question What does it mean to fully factorise? Tap to flip Answer To factorise until the remaining term or terms cannot be factorised any further Question Is 2(3y + 9) factorised? Tap to flip Answer Yes, but not fully Question Is a variable the same thing as an unknown? Tap to flip Answer No: a variable's value is not fixed and can take any value within a range Where this deck sits in the curriculum Curriculum National Curriculum for England Stage Key stage 3 (Years 7–9) Course KS3 Maths Unit Expressions and equations England's National Curriculum sets what is taught; the units and their order are Oak National Academy's.

How this deck was checked On 2026-11-03, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong. Flash Feed is not affiliated with any source named here.
