Re: 2 primes that equal

977 + 23


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Re: 2 primes that equal

Hi;

Too bad you only want two primes

1000 = 29 x 31 + 11 - 37 - 7 x 17+41 x 2 x 3

Re: 2 primes that equal

cube(2) × cube(5) = 1000

(NB: I write cube(n) instead of n[sup]3[/sup] in case the exponent is mistaken for an extra number.)

Oops!  Off to a great start for the new year I am!

Should have been 1997-997. smile

Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional).
LaTex is like painting on many strips of paper and then stacking them to see what picture they make.

7907 - 6907


Prime numbers have got to be the neatest things; they are like atoms. Composites are two or more primes held together by multiplication.
In biology, we use math like we know what we are talking about. Sad isn't it.

Yes, there are more. Why not do a few more before any upgrade.

Re: 2 primes that equal

Version 1.4

Could have an answer of multiples of 100, e.g. 47 + 53.
