Well if your doing math much like how much means add and if it says how much more it means subtract:)
"How much ... all together ?" usually means add. "How much ... left ?" usually means subtract.
It depends on how the rest of the question is worded. If it says "how many were left," for example, that means to subtract. On the other hand, if it says something like "how many were added," it means to add.
