### Why Do We Round Numbers?

Math is a very confusing subject, for sure. But it has many questions and many definitions that are not just easy, but also real fun to solve. If you are wondering as to why we round numbers, there is no answer except that it gives us a better idea of which number we are or will be dealing with.
Let us take a quick review of what rounding off is!
Rounding off is a rough idea of what the value is equal to without having a proper idea of the number. Rounding off numbers requires operating mentally, and often there is no need to get an exact result, instead only an idea or an estimate is required of the outcome.
Here is what you need to do to round off numbers:
Take a look at the numbers.
If the number you need to round is followed by 5, 6, 7, 8, or 9, the number will be rounded up.
For example, the number you have is 48; the rounded up number will be 50.
If the number you need to round is followed by 0, 1, 2, 3, or 4, the number will be rounded down.
For example, the number you have is 44; the rounded up number will be 40.
