(StM:208) Logical Rela7ons •  AND (A and B) •  OR (A, B, or both A and B) •  XOR (exclusive or; A or B, but NOT both) Truth Table Representa7on A F F T T B F T F T Change the representa7on •  •  •  •  A = X dimension in 2D space B = Y dimension in 2D space T = 1 F = 0 We can now express the truth table as points in space.
