What is is 19 and 21 weird?

Is 19 and 21 considered "weird" or unusual numbers? Here's a breakdown:

• 19: While a prime number, 19 doesn't hold any particularly unusual mathematical properties that would make it "weird". It's a fairly ordinary number in mathematical terms.

• 21: Similarly, 21 is not generally considered a "weird" or mathematically significant number. It's a composite number (divisible by 1, 3, 7, and itself). It is, however, the product of two consecutive numbers (3 x 7) which might be considered mildly interesting in some contexts. Also, It can be associated with age in different cultures. For example, In the US, it is considered the legal drinking age.

Therefore, neither 19 nor 21 has achieved "weird" status in popular culture or mathematical lore. They're perfectly normal numbers!
