Back in my early years of uni, we had one of those tests in which every question depends on the previous answer and we had to round every answer to two significant figures. For some stupid reason, a friend and I decided to also use the rounded figure when inputting the values into the next question instead of working algebraically. By the last question, we were off by like 5.
