```Estimated friends:
46137349^22             =  odd
(2*46137349)^22        = couple
(2*46137349+1)^22    =  odd
Then:
46137349^22+(2*46137349)^22-(2*46137349+1)^22 =  couple
But:

The result must be couple and negative.

Estimated friends:

I use the web, http://gmplib.org/, (Demo 1 -- Integer expressions).

I evalue the expression:

46137349^22+(2*46137349)^22-(2*46137349+1)^22

The result was:

40659123321199772708143646506718445599631847521703980877262444624237620050622933969300652398693881381

Nevertheless the real result is:

Negative and couple.

Sorry, I don't understand.

I checked your expression with the demo and the results sure looks
right to me.

If you think there is something wrong, please specify what result you
get and what you expect.
