What are negative numbers and what are they used for? Well, you should know what negative numbers are by now, but incase you didn't, negative numbers are numbers below zero. Although it is below zero, it starts with negative one. A negative number is represented by a minus sign in front of the number. So what's its purpose? A negative number is used to represent anything below zero. For example, it can be seen in the weather forecast. If it's really really really blazing, cold, the temperature could be -1 degrees, because that is pretty cold!
I have seen most negative numbers in equations. For example, while I was learning how to add and subtract negative integers, I learned that you can't subtract negative integers. When you subtract negative integers, you must change the operation to addition, and change the integer into a positive one.
