Surds are irrational roots that are left in exact form rather than written as rounded decimals. Working with surds involves simplifying roots, carrying out calculations and rationalising denominators using algebraic techniques.

Explore our surds worksheets, guides and interactive resources to practise simplifying surds, multiplying and dividing roots and working with exact values at GCSE.
