It costs money to run a free website: our server costs alone are £400 per month. Last year we had 40,000 visitors to the site from whom we received only £40 in donations. We are not currently receiving any other income. At this rate, we will run out of money in the next few months and the site will be forced to close.
Please make a minimum donation of £5 to keep the site going. Thank you

Description
In addition to consolidating subject content from key stage 3, pupils should be taught to:
- apply systematic listing strategies, {including use of the product rule for counting}
- {estimate powers and roots of any given positive number}
- calculate with roots, and with integer {and fractional} indices
- calculate exactly with fractions, {surds} and multiples of π {simplify surd expressions involving squares [for example √12 = √(4 × 3) = √4 × √3 = 2√3] and rationalise denominators}
- calculate with numbers in standard form A × 10n, where 1 ≤ A < 10 and n is an integer
- {change recurring decimals into their corresponding fractions and vice versa}
- identify and work with fractions in ratio problems
- apply and interpret limits of accuracy when rounding or truncating, {including upper and lower bounds}
