Not sure if this will count, but it is correct... in fact, I think its the only solution

I think this is the only way

clarinet89 · 04-1-2009, 06:10 PM

by only using 4s?

rzr · 04-1-2009, 06:25 PM

I swear it worked. I think it went plus or times then division or subtraction then division or subtraction.

**Redorigami** · 04-1-2009, 06:52 PM

You know neither 4 plus 4 nor 4 times 4 gives you a number higher than 19 and dividing and subtracting from there would accomplish absolutely nothing correct?

Unless you somehow made 4x4 into 20 because you were dumb and that would have yielded a correct answer.

**knuckles2224** · 04-1-2009, 06:59 PM

You said the answer got smudged out? I find that hard to believe? Is the answer April fools? or impossible?

**devonin** · 04-1-2009, 08:07 PM

If it's either of those things, you shouldn't have made that thread here.

rzr · 04-1-2009, 08:26 PM

It's not April Fool's. And I the calculator didn't malfunction.

**devonin** · 04-1-2009, 08:35 PM

Using only + - * and / (And thus, no brackets, exponents etc, and taking each to mean and only mean addition, subtraction, multiplication and division?

And not doing something moronic like using the / to go over the = to make "does not equal" ?

**lumphoboextreme** · 04-1-2009, 08:42 PM

haha. yeahhh... you can't get an odd number from all 4's. it's impossible

4*4+4/4 = 17

Idiot.

**foilman8805** · 04-1-2009, 08:55 PM

Also, the only plausible explanation I can give for getting an answer of 19 is an order of operations error that calculators can be prone to if the user neglects to use parentheses (or uses them incorrectly).

**Ground_Breaker** · 04-1-2009, 09:09 PM

I'm pretty sure it's impossible with x=4.

The only way you can get an odd number is with what NinjaKIWI posted, which requires you to divide 4/4 to get 1, and that's not going to leave you with enough to reach 19. Two even numbers, when added, subtracted, multiplied, or divided (except for x/x) will always equal another even number, so you made an error somewhere.

rzr · 04-1-2009, 09:14 PM

What error, Erich?

**foilman8805** · 04-1-2009, 09:16 PM

Order of operations. I just said it was merely a possibility. It may not effect it at all. I really don't think it can be done.

AC1speakerbox · 04-1-2009, 09:19 PM

This problem > Me
(serously though, it can't be done)

**emerald000** · 04-1-2009, 09:23 PM

Well, I ran a little script trying every possible combination of operators (and brackets while at it) and there was no 19 in there. So it is impossible in normal mathematical logic.

So rzr...

Wrecked, give the man (emerald) 5k credits, me as well because I called it first and someone else because you punched the numbers into the calculator wrong and deserve to be out 15k credits.
