2. For the following quantified statement, (a) Write the negation of the statement. (Don't simply put a in front of the statement. Actually rewrite to get a quantified statement that is equivalent to the negation.) Original Statement: Vr e Z. By e Z, az eZ: 72 = y2 + z2. Negation of the original statement: (b) Decide whether the original statement is true or the negation of the original statement is true. Include some brief justification of how you know.

Let D be the domain of 8-bit signed binary numbers, not mathematical integers. Is the following statement true? ∀x ∈ D, ∀y ∈ D, ((x > 0) ^ (y > 0)) → (x + y) > 0 Hint: bear in mind that the + here is addition over 8-bit signed binary numbers (clock arithmetic), NOT standard mathematical addition. Group of answer choices A. Definitely true. B. Definitely false. C. As is, can't tell, but I could tell with further information....
