Left Complementation
Left Complement is similar to negation p. it is a logic operation that basically negates the p. For example if p was a 1 it would not matter what q was the result would be a 0. Likewise if p was a 0 regardless of q the result would be a 1.

Right Complementation
When given a Truth Table, you see two columns of two different values that are related to each other and show opposite relationships, most of the time they are represented by F for false and T for true. Right Complementation is the opposite of the second column, or the right one. When representing each of the results for a 4 by 2 table, there are 16 possible results, one of them being the right complementation, which is actually represented by negation q.
Demonstration of the indicated keyword.
Right Complementation is very similar the Negation P except its Negation Q if you get a combination of P:1 and Q:0 the result will be 1 negating Q and similarly if it is P:0 and Q:1 then the result will be 0. so no mater what P is the answer will always be the negation of Q
The c code block below reflects this.
char NP(char P, char Q) 2 { 3 char x; 4 5 if (Q == 0) 6 x = 1; 7 else 8 x = 0; 9 10 return (x); 11 }
