Ah, rounding numbers can be a peaceful journey! If we look at 150 and want to round it to the nearest 10, we see that it's already quite close to 150. So, when we round 150 to the nearest 10, it stays the same at 150. Just like adding a happy little tree to a painting, sometimes numbers don't need to change much to find their perfect place.
