I don't think so. You write this expression:

((Exposfacto(zootzootplex)![Exposfacto(zootzootplex)]$) = x

(x Exposfacto(zootzootplex)![Exposfacto(zootzootplex)]$) = y (y Exposfacto(zootzootplex)![Exposfacto(zootzootplex)]$) = z

etc.

but you can make the following number: ((Exposfacto(zootzootplex)![Exposfacto((Exposfacto(zootzootplex)![Exposfacto((Exposfacto(zootzootplex)![Exposfacto(...)]$)]$)]$)
