"×" or "⋅" - Page 3

Just go with summations and products :P

So 2×5×677 Posts would be

$\sum_{i=1}^{2}\left (\sum_{k=1}^{5}677 \right )$

$5^2 \times 11 \times 23$ posts could be

$\sum_{i=1}^{11}\left (\sum_{j=1}^{23}\left (\prod_{k=1}^{2}5 \right ) \right )$ posts

I picked the dot option by the way.

So apparently admins prefer the dot method, and mods prefer the x method.

One day to go and the x-confusing × is winning. Come on you mathematicians!

Here is an example of an influential online resource that uses "×":

I use the dot analogically and the star digitally

Would it be possible to make it a profile option so everyone is satisfied?

Not that we know of.

We are toying with the idea of making the selection "random", maybe by using the poll results to weight the decision the code makes.

There is also the `..` and `:` for exponentiation and division
The triangular `therefore` as well as placement of the dots over `variable` quantities for differentiatiion.
Aside from morse code and english grammar, that little dot can be used and construed in a myriad of ways.

wiki educator has the latex symbols:
\cdot
\ddot
\cdotp
\ldotp
\cdots
\ldots
\colon
\vdots
\ddots
\dotsb
\dotso
\dotsm
\dotsi
\dotsc

at very least for symbols with dots.
