Let us give 2 primes that equal 1000. Okay?

863+137

Hi;

Too bad you only want two primes

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

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.)

1997-197 = 1000

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

Should have been 1997-997.

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.

Version 1.3

Any number of primes allowed

Could use a little composite numbers

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

Version 1.4

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