Long, long ago, there was a country called "Country of Integrity." The people of this country were very honest in everything they did, living with integrity. As a result, the country was peaceful, happy, and prosperous.
However, there was an unwritten custom in this country: they disliked negative numbers. They regarded negative numbers as symbols of evil, so they detested seeing negative numbers. They would simply remove the negative sign whenever they saw a negative number. For example, "-1" would become "1."
Xiao Hua is a middle school student who has just moved to the Country of Integrity from another country. Every time he writes a negative number on his math test paper, he gets severely beaten by other classmates and teachers. Can you help him?
