#m=324#

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. # " "(-5)(-7)= 35#

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

Ex. #" "(6)(-4)= -24#

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

Like this, #(-9)(-9) * 4 = +81 * 4 = 324#

Hope that helps!
