... Therefore, if the computer does not generate, then the program syntax is correct and program execution does not result in division by zero. Argument 2: If x is a real number such that x < -2 or x > 2, then x2 > 4. Therefore, if x2 /> 4, then x /< -2 and x /> 2. The common logical form of both of the ...
