The phrase "how much longer" is typically used to inquire about the duration of time remaining until an event occurs or a situation changes. It does not inherently imply addition or subtraction; rather, it seeks to determine the remaining time. For example, if someone asks, "How much longer until we arrive?" they are asking for the time left before arrival, not suggesting any mathematical operation.
