The cards Question In what form is a number written in standard form? Tap to flip Answer A × 10^n, where 1 ≤ A < 10 and n is an integer Question In standard form A × 10^n, what kind of number must n be? Tap to flip Answer An integer Question In standard form A × 10^n, what range must A lie in? Tap to flip Answer 1 ≤ A < 10 (at least 1 and less than 10) Question Why can very large numbers be difficult to read? Tap to flip Answer Because of the number of digits involved Question What can be a more efficient way to write a very large number? Tap to flip Answer In standard form Question In what form is a very small number written in standard form? Tap to flip Answer A × 10^(−n), where 1 ≤ A < 10 Question Why can very small numbers be difficult to read? Tap to flip Answer Because of the number of digits involved Question What does the associative law state? Tap to flip Answer Repeating an operation gives the same result however the pairs of values are grouped Question What can be used to group values when applying the associative law? Tap to flip Answer Brackets Question When converting a number that is not quite in standard form and A is greater than 10, what happens to the index of 10? Tap to flip Answer You add to the index the multiplications of 10 needed to bring A below 10 Question What does the commutative law state? Tap to flip Answer You can write the values of a calculation in a different order and the result is still the same Question Which two operations does the commutative law apply to? Tap to flip Answer Addition and multiplication Question Which two operations does the associative law apply to? Tap to flip Answer Addition and multiplication Question How can a number that is multiplied by itself several times be written more simply? Tap to flip Answer In exponential form Question When adding numbers in standard form, what is an important consideration? Tap to flip Answer Place value Question When is it easy to add two numbers in standard form? Tap to flip Answer When the power of 10 is the same for both numbers Question When is it easy to subtract two numbers in standard form? Tap to flip Answer When the power of 10 is the same for both numbers Question When adding numbers in standard form, should you also add the powers of 10? Tap to flip Answer No: the magnitude does not change to the sum of the powers of 10 Question What chart can support correct addition or subtraction of large or small numbers in standard form? Tap to flip Answer A place value chart Question Which law allows the product of two numbers in standard form to be easily calculated? Tap to flip Answer The commutative law Question When multiplying in standard form, what do the index laws let you do with powers of the same base? Tap to flip Answer Combine them Question When multiplying numbers in standard form, what mistake is made with the number parts (coefficients)? Tap to flip Answer Adding them as well as the exponents; the number parts should be multiplied (group the number parts together and the powers together) Question What can be used to calculate the quotient of two numbers in standard form? Tap to flip Answer Equivalent fractions Question When dividing numbers in standard form, how can you avoid wrongly changing the × between the number and the power of 10 into ÷? Tap to flip Answer Write the division as a fraction Question What can standard form calculations be done with? Tap to flip Answer A calculator Question Why is it useful to do arithmetic directly on numbers written in standard form? Tap to flip Answer It reduces error during conversion Question When finding the mean of numbers on a calculator, what common error is made? Tap to flip Answer Leaving out the brackets when summing the values Question To avoid calculator errors when finding a mean, what should you record before dividing by the number of values? Tap to flip Answer The sum of the values Where this deck sits in the curriculum Curriculum National Curriculum for England Stage GCSE (Years 10–11) Course GCSE Maths Unit Standard form calculations Tiers foundation and higher England's National Curriculum sets what is taught; the units and their order are Oak National Academy's.

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