Casio ClassWiz CW Tutorial: Harder Fraction Calculations

Learn how to perform harder fraction calculations using ClassWiz scientific calculators. This tutorial demonstrates how to work with more complicated fractions, including mixed numbers and calculations within fractions when using the sine rule, helping students solve multi-step fraction problems accurately and efficiently. Designed for GCSE and A-Level Mathematics, this lesson develops essential number and algebra skills that are used throughout the mathematics curriculum. Viewers learn how to enter and evaluate advanced fractional expressions correctly, reducing the risk of calculation errors and improving confidence when working with increasingly complex mathematical problems. These skills are particularly valuable when simplifying expressions, solving equations, and checking solutions efficiently. The procedures are demonstrated using the fx-991CW, but can also apply to the fx-83GTCW, fx-85GTCW, and all CW+ models. Mastering these tools can improve speed, accuracy, and confidence in mathematical problem solving, making them especially useful for revision and effective exam preparation
