On a four-square Veitch diagram, a two-
variable term, such as
AB, CA, EB, OK,
AC, etc., occupies only one square.
terms (AB and AB).
Each term contains two
variables; therefore, each two-variable term
will occupy only one square on a four-square

diagram, work only
one term at a time.
Start with the first term on the left (AB).
As stated previously, a two-variable term
occupies only one square on a four-square
To determine the proper
square, take each variable of the term (AB)
and determine which square is common to both
variables as follows:
