Thanks LarryHL for the correction. I was in a hurry to post my answer and get back to work that I overlooked the final answer, lol. I did however come up with another one that you might agree will work. adjust the angle of the top match that helps make up the equals sign so that we end up with 23/7 > 2.

haha, that works =P

[aesculapius]

that does seem ideal but by definition of an equation that answers fails to satisfy the requirement that the answer too must also be an equation. what you provided is an inequality which contrasts from an equation. if your answer is acceptable as is many other possible answers which turns the equal sign to a inequation sign "?"

Actually aesculapius, these are all accepted symbols to make up a well formed equation.
< less than
> greater than
>= greater than or equal to
<= less than or equal to
!= not equal to
= equal to
~= approximately equal to

And the reason the XIIII / VII = II is not correct is because you would actually have XIII / VII = II or X/III / VII = II. If you move the other match to be straight then you have moved 2 matches. XIII is another way to write X-III, so one answer would be X-III/VII = II and this is not a valid equation. 7/7 is not 2. The other answer would come out as (10/3)/ 7 = 2 but
is doesn't equal 2 but rather 0.476 (it actually goes on beyond 3 decimal places). I might be a little off on that, i did it real quick and might have missed a rule on that one lol.

OMG. I totally hate this site. Every day its something new that doesn't make any sense. Why don't you guys come up with some real brain teasers or copy some from a book or something. This is retarded. It does not equal pi. Thats as good as saying:

XXII
------ = III because we'll just round that one down pretty hard core to make it work
VII

or

XXII
---- = II because were just gonna truncate that .75 so that this works.
VIII

this is dumb; we cant just go ahead and round down or truncate whenever we feel like it just to make a sorry attempt at a brain teaser. Common, just try a little bit. Just a little.

Totally agree. No wonder kids have trouble understanding Algebra when we treat the equal sign like this!

[Mr. Alighieri]

simply take one matchstick from the bottom # making it six and move it to the top making that # 24 then 24 / 6= 2

[inmymemory919]

Why not just do this? Take 1 matchstiock aweay from the top and lay it over the equal sign so it becomes "not equal"

What about XXI + I / VI = II
