BOTH of those. Understand that multiplication has "precedence" over additions and subtractions.

-15 + 3 x -4 - 12 /-6

The 3x stays as it is.

You CANNOT subtract the 12 from the -4 because DIVISION has precedence over addition or subtraction.

In your given expression, change ALL numbers to their signed forms, and use Commutative Property of Addition to combine like-terms.

Maybe you meant the "x" to be multiplication operation symbol. If this be so, then as you go from left to right in the entire expression, to operations you do first must be the and the ; this makes your expression now like this:

and you now again start from left to right and do the additions or subtractions.
