$m = 324$

#### Explanation:

It seems like you are having trouble multiplying and dividing by negatives.

A negative number times a negative number will always result in a positive number.

Ex. $\text{ } \left(- 5\right) \left(- 7\right) = 35$

A positive number times a negative number will always result in a negative number.

Ex. $\text{ } \left(6\right) \left(- 4\right) = - 24$

And lastly you probably already know that a positive number times a positive number will result in a positive number.

Like this, $\left(- 9\right) \left(- 9\right) \cdot 4 = + 81 \cdot 4 = 324$

Hope that helps!
