The cards Question What is a vinculum? Tap to flip Answer The horizontal line placed over an expression to show that everything below it is one group. Question In a fraction, what does the fraction bar represent? Tap to flip Answer Division. Question If dividing the numerator by the denominator gives a non-terminating decimal, what is that decimal? Tap to flip Answer An approximation of the fraction. Question To turn a decimal into a fraction, what denominator can you first write it over? Tap to flip Answer A denominator of one; then use equivalent fractions. Question When ordering decimals, is the one with more significant figures always the greater number? Tap to flip Answer No; writing them with the same number of decimal places shows their size more clearly. Question What does any non-zero number multiplied by its reciprocal equal? Tap to flip Answer 1 Question What can help reduce the complexity of calculations with fractions? Tap to flip Answer Equivalent fractions. Question What are prime factors? Tap to flip Answer The factors of a number that are themselves prime. Question What does expressing a number as a product of primes mean? Tap to flip Answer Writing it uniquely as a product of its factors that are prime numbers. Question Can every positive integer be written as a product of its prime factors? Tap to flip Answer Yes. Question How can a product of prime factors be simplified? Tap to flip Answer By using index notation. Question When decomposing a number into primes, which operation joins the prime factors? Tap to flip Answer Multiplication (not addition). Question What does HCF stand for? Tap to flip Answer Highest common factor. Question What does LCM stand for? Tap to flip Answer Lowest common multiple. Question How can both the LCM and the HCF of numbers be found? Tap to flip Answer By comparing the prime factorisations of the numbers. Question Which diagram can be a helpful representation for finding the HCF and LCM? Tap to flip Answer A Venn diagram. Question What is another word for an exponent? Tap to flip Answer Index (plural indices). Question What do integer indices state? Tap to flip Answer How often a number should be multiplied by itself. Question What kind of number is the square root of any perfect square? Tap to flip Answer An integer. Question How can you estimate the square root of a number? Tap to flip Answer Compare it with the square roots of the closest perfect squares. Question Is any number a square number just because it can be squared? Tap to flip Answer No; a square number is the result of multiplying a number by itself. Question What is the absolute value of −5? Tap to flip Answer 5 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 Every subtraction can be rewritten as what? Tap to flip Answer An addition of the additive inverse. Question The rules for multiplying with negative numbers can be extended to which operation? Tap to flip Answer Division. Question Does addition always make the result bigger? Tap to flip Answer No. Question 16 is which power of 2? Tap to flip Answer The fourth power: 2^4, read as '2 to the power of 4'. Question What is a numerical coefficient? Tap to flip Answer A constant multiplier of the variables in a term. Question When is an operation commutative? Tap to flip Answer When the values it operates on can be written in either order without changing the calculation. Question When is an operation associative? Tap to flip Answer When repeating it gives the same result however pairs of values are grouped. Question What is the index law for multiplying powers with the same base? Tap to flip Answer a^b × a^c = a^(b+c) Question When multiplying terms with coefficients, are the coefficients added like the exponents? Tap to flip Answer No; the coefficients are multiplied. Question What is the index law for dividing powers with the same base? Tap to flip Answer a^b ÷ a^c = a^(b−c) Question When dividing terms with coefficients, are the coefficients subtracted like the exponents? Tap to flip Answer No; the coefficients are divided. Question What is the index law for raising a power to a power? Tap to flip Answer (a^b)^c = a^(bc) Question When raising a bracketed term to a power, what must be raised to the power besides the power term? Tap to flip Answer The coefficient: everything in the bracket is affected by the power. Question What is any term with an exponent of zero equal to? Tap to flip Answer 1 Question Why is 8^0 equal to 1? Tap to flip Answer 8^4 ÷ 8^4 = 8^0, and any number divided by itself gives 1. Question What does a negative exponent tell you? Tap to flip Answer How many times you need to multiply the reciprocal of the base. Question Where do negative exponents appear when writing numbers? Tap to flip Answer When writing very small numbers in standard form. Question In index laws, what can the base be? Tap to flip Answer A number, a letter or a combination of the two.

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.
