Re: Make 1000 using 8 8s

Hi goodwinrobert;

While looking to see whether my solution is new ( which I doubt because of it's simplicity ) I came across this page.

Aginis' solution is brilliant.

Here is mine:


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.

Hi G-man;

How does that equal 1000?

Re: Make 1000 using 8 8s

phrontister's "CONCATENATE" one is not a solution.
What amounts to (1, 0, 0, 0) is not 1000, so it does
not count.


Signature line:

I wish a had a more interesting signature line.

Re: Make 1000 using 8 8s

Hi reconsideryouranswer;

The concantenate command does exactly that: conc(1,0,0,0) = 1000.

Re: Make 1000 using 8 8s

Sorry if this was already mentioned, I didn't see it smile

(8x8 +8x8)x8 -8 -8 -8
= 8(64+64) -24
= 1024-24
=1000
