Mathematics: Principle of inclusion and exclusion
By: Jay O'Toole
Mathematical Inclusion and Exclusion can be stated as The Law of NonContradiction. "If A, then not B." "If this, then no other answer is possible." For instance, 1+1=2; 2+2=4; 3+3=6; 4+4=8; 5+5=10. 2X will always be equal to the number added to itself...
