Question 946404
{{{cross(P=2l+2w)}}}


This says, "one is one":  {{{l=1}}}
This say,s "one is one":  {{{1=1}}}
What is the difference?    The first one used a different character and key than the second one, for the left-hand member.  Some people CAN misread the "l", and often enough, WILL misread.
