What is the value of c if $x\cdot(3x+1)
In this context, c doesn't stand for an abbreviation of a number .
\cdot is the LaTeX command used to produce a centered dot (⋅)
to indicate the multiplication function.
The example in the question could be written as x • (3x+1) if you
use Alt-0149 on the keypad to insert the dot instead of \cdot.
Read it as "x times the quantity three x plus one".
