  • $\begingroup$ @AJ if anyone, you should explain in an answer just as it is explained in the link (as well as including the link, itself, for credibility) :P $\endgroup$ – Mr Pie Aug 27 '18 at 11:10

    $\begingroup$ As the puzzle is now stated, there are several ways to "prove" this, and no way to tell, which of them is the one intended as correct. This makes the puzzle too broad, so maybe include some additional constraints on allowed proof methods? Moving the goalposts (so that otherwise valid answers get retroactively disqualified) is generally frowned upon: it's better to add the constraints beforehand, and then accept any answer that fits all of them, even if the answer wasn't the one you intended. $\endgroup$ – Bass Aug 27 '18 at 11:16

Answer 1:

Since there is no base specified, I'm going to pick base 12.
$7_{12} + 7_{12} = 12_{12}$

Answer 2:

Roman numerals..

My lateral thinking:

7 = VII
Flip it and you also get 7 = ΛII
put them one under the other like you learned in school and you get
VII
ΛII
put them really close together and you get
XII = 12.

12 what?

If you ask for corners yes it´s true. The number 7 has 6 corners,
so 6 corners + 6 corners = 12 corners

Suppose that

It is $12$:$00$ on an analog clock.

Then,

Once the clock strikes $1$:$00$, the big hand would have moved directly above the small hand. Let's call this position $1$.

When the clock strikes $2$:$00$, we now have a total of $1+1$ positions, which is $2$.

The pattern is obvious; when the clock strikes $7$:$00$, the big hand would have moved directly on top the small hand $7$ times.

Note that

O'clock means $12$.

Therefore,

$7+7=12$.
