Rewrite the following conditional expressions without any NOT operators so that the logical outcome is unchanged for all values of the variable x. Then evaluate the original expression and the equivalent expression using the values: x = 1, y = 1, z = 1. Compare the results.
Notes: The NOT operator applies to the part of the expression enclosed in parentheses that follows immediately.
Evaluating the original and equivalent expressions for the values given is only a partial check. A general check can be done with a truth table.
(x > = 3) OR NOT (x = 1) (x>=3)0R(x<>1)
Evaluate original F OR NOT (T) =FORF =F
Evaluate equivalent F OR F F (Both are the same
