SUMMARY

The discussion centers on Ulam numbers, defined as numbers that can be expressed uniquely as the sum of two distinct Ulam numbers. Participants seek to generate a list of the first 20 Ulam numbers and inquire about formulas for their calculation. A program is suggested to generate all Ulam numbers below a specified limit, with a focus on finding those less than 1000. Additionally, the conversation touches on the relationship between Ulam numbers and prime numbers, emphasizing the need for clarity on the definition of prime numbers.

What are Ulam #'s? A ulam #, if an only if it can be written uniquely as the sumof two distinct Ulam #'s. ?

I need to make a list of the firts 20 Ulam #'s. I got the first 8. It's there any formanula or something easy to do it?

How many Ulam number are thre? Prove answer




EXTRA HELP!

Write a program that will generate all Ulam #'s less than a given number n. Use your progam to find all the Ulam numbers less than 1000. I am not good with calculator plus I don't have manual, I have a TI-83.:confused:

How many are there? ?

What portion of these are prime? Prime is a number divisible by one and by itself only... right?
