GCSE Secondary Maths Age 13-17 - Algebra: Indices - Explained

The video tutorial covers the topic of indices, focusing on the power of zero, negative indices, and ordering numbers. It explains that any number raised to the power of zero equals one and demonstrates how to handle negative indices by converting them into fractions. The tutorial also guides viewers on how to order numbers by converting them into a comparable form, either as ordinary numbers or in standard form.
