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 teh equivalent expression using the valuess x = 1, y =1, z = 1. Compare the results.
1) NOT (x < = 3) OR NOT (x = 1)
2) NOT (x > = 1 AND x < = 4)
3) NOT (x) < > 2 AND x < > 3)
