Hi @Muhammed_Hadi.T,
I’m sorry to hear that you found this lesson confusing.

The basic idea behind rounding is to shorten a number and get rid of any digits that we don’t really care about.

For example, we may have the result from some calculation that includes a bunch of decimal points. However, we may only care about the whole number part - usually to make it easier to write down or display.

When this need arises, we can use rounding to remove any of unnecessary digits.

Let’s imagine that we did some calculation that resulted in the answer 3.75, and we want to round this to a nearby whole number.
The two most likely candidates would be to round it to either 3 or 4, so which one do we chose?

This is where the techniques I mention in the video come in but traditionally this would be rounded to 4.

I hope this helps clarify things but if you have any specific questions regarding the rounding techniques covered in the video then please do let me know.
