What’s the significance of your favourite number?

Have you heard of the phrase “you are unique, just like everyone else”? Hehe. Well for this entry I’m gonna let you know that every number, there’s something significant to itself, means it’s only true to that number.

My favourite number is 18, what’s so special about this is it is the only number that is twice the sum of its digits. Meaning 18 is (1+8) x2. Hehe I’ll just believe this statement since I don’t want to go and calculate every numbers from 10 - 99.

Here are the first 10 digits and it’s significance.


0 is the additive identity.
1 is the multiplicative identity.
2 is the only even prime.
3 is the number of spatial dimensions we live in.
4 is the smallest number of colors sufficient to color all planar maps.
5 is the number of Platonic solids.
