Question

1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 - 1 + 1 + 1 + 1 + 1 + 1 x0 = ?

Answer 1

This question has been on Facebook lately and the answers were 0 or 13. Also notice that there's a - in it.

Answer 2

The last term is the only one being multiplied by 0? Or should there be parentheses around it and then a "times 0"?
It seems like this would be the case in what is written.
\[1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 - 1 + 1 + 1 + 1 + 1 + \cancel{1 *0} \]

Answer 3

Which does turn out to be 13.

If it looked like this
\[(1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 - 1 + 1 + 1 + 1 + 1 + 1)\times0 \]
We'd have 0 because anything multiplied by 0 is 0.
\[\cancel{(1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 - 1 + 1 + 1 + 1 + 1 + 1)\times0} ~~~\color{green}0 \]

Answer 4

\[\cancel{\text{facebook}}\]
