Probably a geometric series question

Click For Summary
SUMMARY

The mathematical expression 2^32 – {(2 + 1) (2^2 + 1) (2^4 + 1) (2^8 + 1) (2^16 + 1)} simplifies to 1 when correctly interpreted. The initial confusion arose from a misstatement of the problem, where the original expression incorrectly used subtraction instead of addition in the second term. The correct application of the formula (1+x)(1+x^2) = (x^4-1)/(x-1) leads to this conclusion.

lol solved... there was an error in question statement:
question was 2^32 – {(2 + 1) (2^2 + 1) (2^4+1) (2^8+1) (2^16+1)}
(1+x) (1+x^2) = (x^4-1)/x-1
using this iteration yields answer as 1
thanks anyways :)
