Ah of course and that makes far more sense.
Adding this prime to the end of a number guarantees a composite.
I wonder if that is a property the belongs to primes, or if there are non-trivial composite examples (any number ending in 2 has this property).
- bodhiandpysics1 6y agoYou can rephrase that conjecture to say... given any sequence of digits not ending in 2 (or 0), is there a prime number that ends in that sequence. That's an interesting conjecture!
- bodhiandphysics 6y agoAcchhh!!! Brain fart!!!
- Cogito 6y agoyes I like that phrasing. Similarly we can say there is a class of primes that have this property, what other classes of numbers also have this property?
