Rewrite each statement without using quantifiers or variables. Indicate which are true and which are false, and justify your answers as best as you can.
Exercise
Let the domain of x be the set D of objects discussed in mathematics courses, and let Real(x) be “x is a real number,” Pos(x) be “x is a positive real number,” Neg(x) be “x is a negative real number,” and Int(x) be “x is an integer.”
a. Pos(0)
b. ∀x, Real(x) Neg(x) → Pos(−x).
c. ∀x, Int(x) → Real(x).
d. ∃x such that Real(x) ~Int(x).
