Question 1097235
.
Twice a number is no less than 10 units from -1
~~~~~~~~~~~~~~~~~~~~~~


For me, it is a MYSTERY what this post/this condition means . . . 



And the best service from my side to the author of this post is to say that this formulation is mathematically incorrect . . . 


In my view, not only it is mathematically incorrect formulation.
It is incorrect from the English grammar, word usage and the sentence construction point of view, too . . . 



But if you change it in this way

<pre>    
    Twice a number is {{{highlight(located)}}} no less than 10 units from -1


           or even better


    Twice a number is {{{highlight(located)}}}/{{{highlight(remoted)}}} no closer than 10 units from -1
</pre>

then everything will be in place . . .
