# Linear Algebra/Complex Representations

From Wikibooks, open books for an open world

Recall the definitions of the complex number addition

and multiplication.

- Example 2.1

For instance, and .

Handling scalar operations with those rules, all of the operations that we've covered for real vector spaces carry over unchanged.

- Example 2.2

Matrix multiplication is the same, although the scalar arithmetic involves more bookkeeping.

Everything else from prior chapters that we can, we shall also carry over unchanged. For instance, we shall call this

the **standard basis** for as a vector space over and again denote it .
