We formulate a formal syntax of approximate formulas for the logic with counting
quantifiers, $\mathcal{SOLP}$, studied by us in \cite{aaco06}, where we showed the
following facts:
$(i)$ In the presence of a built--in (linear) order, $\mathcal{SOLP}$ can
describe {\bf NP}--complete problems and fragments of it capture classes like
