## Simplify expressions with Kronecker delta

Here you practice the properties of the Kronecker delta by simplifying given expressions as much as possible.

I am Alexander Fufa*eV*, physicist and owner of Universaldenker world. Here you can find **high-quality** and **free** content about **physics**. What are you waiting for?

A course is an ordered learning unit that will take you step by step through a comprehensive physics topic so that by the end you will have mastered it.
