# 'Parity' of Functions

Algebra Level 2

We all know that by parity of integers,

$\text{ odd number + odd number = even number } \; .$

Then $\text{ odd function + odd function }$ is always an $\text{\_\_\_\_\_\_\_\_\_\_}$.

Clarification: The function in question is for $\mathbb R \to \mathbb R$.
