1 + 1= 2 1 - 1=0 1 * 1 is 1 and 1 divided by 1 is 1 take all four answers and add them together and you get four. Four is the first square, two times two equals four...... Now two plus two is four 2 - 2 is zero though 2 * 2 is 4 2 / 2 x 1... When adding a squared number 3 * 3you could do this for any number and it'll give you the square up the following number

How would you write that into something I can run on a computer

My number work for 2 digit 3 digit use 232792560

2520/77=327+3/11 11 is denominator so this is not prime since it's not 77

25200/91=276+12/13 13 is not 91 so it's not prime

25200/143=176+32/143 143 is the denominator so yes this is primesee

Well I've been crunching numbers and I figured out a way to pull the pr do I have an answer for the primes problem now all you have to do is take the number 2520 and divided by any number that is two digit add another zero if you want to do three digits add another zero if you want to do for digits add another zero if you want to do 5 digits and if the denominator of the mixed fraction is the same as the number you divided into my special number then it is a prime bottom line I've tried every prime so far has worked example 25200/101=. 249 51/101. just ignore the rest of the number and noticed the denominator is 101 so therefore it must be prime and only then is it prime

Prayer changes things and gives results

What is the first prime it misses?

hi Knewlogik

Welcome to the forum. you've made two similar posts so I'll try to deal with both here.

If you start with 7 and keep adding 6 you get:

7, 13, 19, 25, 31, 37, …..

Starting with 11 gives:

11, 17, 23, 29, 35, 41, …..

Will you ever get the same number in both lists? No; it'll never happen.

Because the two lists start 4 apart and both go up at the same rate, they never share a value.

Do you know about straight line graphs? If not look here:

https://www.mathsisfun.com/equation_of_line.html

The first sequence has equation y = 7 +6x. The second is y = 11 + 6x

These two lines have the same gradient (6) so they are parallel. So they never cross.

For many, many years mathematicians have tried to find a formula for generating primes. There are a few that give some primes, and many that look like they are working but then fail, but nobody has yet come up with a formula for all primes. I suspect it doesn't exist but I don't think there is a proof that no such formula exists.

Best wishes, keep safe,

Bob

1,2,3,4,5,6

7,8,9,10,11,12

13,14,15,16,17,18... Now pretend that this is an infinite row that continues downward but instead of stopping at the tent position we're stopping at the sixth position and starting over Seven second line but would normally be the 10th position is now the 7th position and while adding 6 to the 7th line and where the position 7,11 is lying you will forever have all primes with some extras correct ex 07,13,19,25,31,37... 11,17,23,29,35,41,47... Does that make more sense now if you have graph paper you have all those numbers inside of each box with what he leaves you with is a straight line down both 11 and 7 throw with all primes including a couple extras how do I do window out the non primes
