A student claims she can prove that subtraction of integers is commutative. She points out that if a and b are integers, then a - b = a + b. Since addition is commutative, so is subtraction. What is your response? Choose the correct answer below. A. The student is incorrect. Although a - b = a + b, the argument is not complete because a - b = a + b and b-a = b + -a and a+ - b‡b + -a. B. The student is correct. Subtraction is commutative because a-b=a+b and b - a = b + -a and a+b=b+ - a.
a. Make a truth table for p -a (the inverse of p → q). Your first two columns should be the same as the first two columns of the table for p - q. The last columns of the two tables should be different. Are they? Is ~p → ~q logically equivalent to p q? b. Compare the truth table for ~p - ~g (the inverse of p - q) with the truth table for g-p (the converse of p - g). Are the last columns the same? Are the inverse and the converse logically equivalent?
Determine whether these are valid arguments. a) If x2 ≠ 0, where x is a real number, then x ≠ 0. Let a be a real number with a2 ≠ 0; then a ≠ 0.
Can someone help with this please?
Statement: If p is prime, then p2 is composite. A. State the converse, contrapositive, and inverse of the statement. B. Which pairs of statements are logically equivalent to each other?
