to express oneself mathematically

 when a piece of charcoal in ones hand
to express oneself on a wall demand
a path chosen can be any
this time round in numerals many.

the mathematics of things all
to understand an order tall
for, if one plus one is definitely two
i ask though, if that holds true.

for in the throe of lovers deep
nine moths later in we peep
it seems there is a number three
of one plus one this came to be.

so now u tell me the math of things
to the table much it brings
but the variation of formulas best one knows

 it helps with the complexity of life that grows.
