A negative number is a number on the left side of the number line. It is the opposite of a positive. To use these numbers you can find out things like how much money you owe. For example, say you owe someone 50 dollars you would be down 50 dollars so it will be negative 50 dollars. Another example you go to your bank and withdraw 100 dollars. You will be down 100 dollars so it is negative.
People use these numbers all the time for real life problems. You can use them to figure out how much money you owe or how big of a profit you made. It may not seem like it but we use negative numbers all the time. and, surprisingly negative numbers are like negative connotations in literature. If you have to many negative connotations in a sentence then it won't be a great sentence. Same with numbers if you have to many negatives that you owe your credit won't be good.
