Negative numbers are real numbers that are less than zero. That usually mean that when you subtract a bigger number than the other number. For example, lets say : 2-6. Six is bigger than two so you can't subtract without having to go into the negatives. Before, in school the teachers would not let us solve those kinds of equations because they were not possible. That is only what they said because we still did not know about the negative numbers. So in other words, negative numbers are leftovers that you di not have enough to take away. The sign - represents negative numbers.
     In real life negative numbers are usually bad. Let's take that as someone owing money. In real life negative numbers can be referred to money in banks. Like when someone owes money to the bank, the money they owe is represented as negative numbers. So now you know what real numbers are and how they are used in real life situations. Also, negative numbers usually mean debts, so in really life they are bad. You have to have positive numbers in real life because if you have negatives you are in trouble.
