Math Definitions - Letter I

An identity is an equation that is always true, regardless of the values of the variables chosen.

For example, \(\sqrt[3]{a^3} = a\) is always true, regardless of the value chosen for \(a\).

Students learn a new math skill every week at school, sometimes just before they start a new skill, if they want to look at what a specific term means, this is where this dictionary will become handy and a go-to guide for a student.
