The cards Question What are like terms? Tap to flip Answer Terms that have the same set of variables with the same corresponding exponents. Question What does it mean to fully simplify an expression? Tap to flip Answer To write it so compactly that it cannot be simplified any further, without changing its value. Question When multiplying variables together, in what order should you write them so that like terms are easier to spot? Tap to flip Answer In alphabetical order. Question In algebra, what is substitution used for? Tap to flip Answer Replacing variables with values. Question When substituting a value into an expression, what should you always put around the value? Tap to flip Answer Brackets; this helps avoid mistakes, including when using a calculator. Question In algebra, what is a term? Tap to flip Answer A single number or letter, or the product of numbers and/or variables. Question What separates the terms in an expression? Tap to flip Answer An operator (+ or –). Question What is an equation? Tap to flip Answer A statement that two expressions are equal, shown by =. Question What is an identity? Tap to flip Answer An equation that is true for all values of the variables. Question Which symbol is used to show that two expressions are equivalent and form an identity? Tap to flip Answer ≡ Question What is a formula? Tap to flip Answer A mathematical rule or relationship connecting two or more variables. Question If d is the number of days and w is the number of weeks, what is the formula for d? Tap to flip Answer d = 7w Question What does the distributive law say? Tap to flip Answer Multiplying a sum is the same as multiplying each addend and then adding the results. Question In algebra, what is a factor? Tap to flip Answer A term which exactly divides another term. Question What does it mean to factorise? Tap to flip Answer To express a term as the product of its factors. Question When is an expression fully factorised? Tap to flip Answer When the highest common factor has been taken out. Question What is an interior angle? Tap to flip Answer An angle formed inside a polygon by two of its edges. Question Vertically opposite angles are formed where two lines intersect. How do they compare in size? Tap to flip Answer They are equal. Question Are 2(x + 4) and 2x + 4 equivalent expressions? Tap to flip Answer No; testing a value such as x = 5 in each shows that they differ. Question What is the additive inverse of a number? Tap to flip Answer The number that, added to the original number, gives a sum of 0. Question What does any non-zero number multiplied by its reciprocal equal? Tap to flip Answer 1 Question If a linear equation contains brackets, must you always expand them first? Tap to flip Answer No; you can divide each term instead, which may be best when all terms share a common factor. Question What is the subject of a formula? Tap to flip Answer The variable expressed in terms of the other variables, with an exponent of 1 and a coefficient of 1. Question When you rearrange a formula for a variable, what do you find instead of a value? Tap to flip Answer An expression that the variable is equal to. Question What is a binomial? Tap to flip Answer An algebraic expression that is the sum or difference of exactly 2 unlike terms. Question What is a partial product? Tap to flip Answer Any of the multiplication results that lead up to an overall multiplication result. Question When multiplying two binomials, which terms must be multiplied together? Tap to flip Answer Both terms in one bracket must be multiplied by both terms in the other. Question Using the distributive law, how can (x + 2)(x + 3) be rewritten? Tap to flip Answer x(x + 3) + 2(x + 3) Question What is a quadratic? Tap to flip Answer An equation, graph or sequence in which the highest exponent of the variable is 2. Question How can you check the factors you have found for a quadratic? Tap to flip Answer Multiply them out and check the product against the quadratic. Question What is the absolute value of a number? Tap to flip Answer Its distance from zero. Question Is squaring each term the correct way to expand (x + 3)²? Tap to flip Answer No. Question Can a quadratic whose x term has a coefficient of zero still be factorised? Tap to flip Answer Sometimes, yes: for example by using the difference of two squares. Question What is a solution to an equality with one variable? Tap to flip Answer A value of the variable which, when substituted, keeps the two expressions equal. Question A parabola is a curve on which every point is an equal distance from which two things? Tap to flip Answer A fixed point (the focus) and a fixed straight line (the directrix). Question If the product of two binomial expressions equals zero, what must be true? Tap to flip Answer One of the two binomial expressions must equal zero. Question After factorising a quadratic equation equal to zero, how do you find the values of x? Tap to flip Answer Set each bracket equal to zero and solve; the solutions are not just the constants in the brackets. Question Besides algebra, what can the difference of two squares be used for? Tap to flip Answer Quickly calculating numerical expressions. Question Why should you substitute your solutions back into the original problem? Tap to flip Answer To check them and to see whether they are valid in the context.

How this deck was checked On 2026-11-02, 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.
