In this Math tutorial, you will learn:
Imagine the following scenario: A friend tells you that he owns $50,000 less than his brother. Is this information sufficient to draw a conclusion about their wealth? In other words, is it certain that your friend is poor and his brother is rich?
Obviously, the answer is NO. Your friend may be broke; in this case, his brother owns $50,000. This means none of them is rich but your friend's brother is economically stable. However, another option is that the two brothers may be both rich, as your friend may own 10 million USD of wealth and his brother just $50,000 more.
Therefore, it is not sufficient to know how much a quantity is greater than another to draw conclusions about their respective sizes. Therefore, we need other types of comparison to have a better information and understanding about quantities.
