A plot should be described with as few terms
b.
two
as possible.
Each term should contain as
few
c.
three
variables as possible.
These four squares
represent the term B.
On the same Veitch
diagram, these four
squares represent the
term C.
All six plotted squares combined are
described as B+C.
Notice that the lower corner squares are used
twice, allowing two groups of four squares,
each described by a one-variable term.
Referring to the top diagram above, this plot
could have been described as follows: The
shaded area is described as B.
The two
unshaded squares could be described as BC and
would result in a plot described as B+BC.
One term now contains two variables (BC).
Which of the following expressions is
simpler?
a.
B+C
b.
B+BC
