The parenthesis are used to keep the negative signs with the numbers so they won't be mistaken for subtraction, and in this case they also mean multiplication. This equation consists of 3 variables multiplied together. It could also be written as:
-x times -3y times -z = ?
or
-x * -3y * -z = ? where * is used as the times operator instead of x so it isn't confused with the letter x.
The parenthesis are commonly used in math for multiplication.
Good Luck!

you multiply the 3 terms together:
-x times -3y = 3xy
(because two negatives make a positive)
3xy times -z = -3xyz

means that you got to multiply(-x) by (-3y) by (-z)
It's like it was : (-X) x (-3Y) x (-z) wich equals (3XY) x (-Z) which equals to -3xyz

the answer is -3xyz. everything is multiplied, and if you had numerical values for x, y, and z, you would have purely a numerical answer.
