expression are applied to

a 16-

square Veitch

c.

diagram as for an eight-square diagram.

To

d.

GH

extract the simplified expression, describe

the plot with as few terms

and as few

variables as possible.

Look for patterns of

plotted squares in the following order of

preference:

a.

Eight plotted squares which describe a

one-variable term.

b.

Four plotted squares which describe a

two-variable term.

c.

Two plotted squares which describe a

three-variable term.

d.

One plotted square which describes a

four-variable term.
