Paper 2 of the Edexcel IGCSE Mathematics exam allows a scientific calculator, and knowing how to use it efficiently can save valuable time. Entering complex expressions correctly, using memory and fraction keys, and interpreting the display are all skills that separate a confident candidate from one who wastes marks on input errors.

This topic covers the key functions of a scientific calculator, from entering standard-form numbers to using the ANS key for multi-step calculations.
