Some numbers feel special because they show up a lot in the world around us. Like 7, which can be found in the days of the week or in rainbows, there are seven colors! Or 13, which people sometimes think is unlucky, but it's also interesting in math. These numbers don’t just appear by accident; they help make patterns we find everywhere.
Examples
- A rainbow has seven colors, just like there are seven days in a week.
- Some people believe that the number 13 is unlucky because it comes after twelve, which feels complete.
- There are often 7 wonders of the world, not always exactly 7, but close enough to feel special.
