=$- 1100$

#### Explanation:

The only operation here is multiplication of positive and negative integers.
Work out the sign first: There are three negative signs, this is an odd number, so the final answer will be negative.

$- \left(22\right) \left(- 5\right) \left(5\right) \left(- 2\right)$

=$- 22 \times 5 \times 5 \times 2$

=$- 110 \times 10$
