Don't worry just break it down and it becomes easier. So picture a number line, at -11 . To take away 8 it means move to the left 8 spaces. This leaves u with -19. Then negative 19 plus positive 19 cancels each other out to leave 0. Finally, using the number line again, 0 take away 6 will leave u with -6
Note that -11 - 8 = -19 and we have + 19 so they cancel each other out leaving -6.

to me 19(-6) means 19 x -6 = -114
