(2) Find a pair of numbers that provides a counterexample to show that the given statement is false.
(a) If the sum of two counting numbers is an even counting number, then the product of the two counting numbers is an even
counting number.

What is the value of x after each of these statements
a. if x+2=3 then x:=x + 1
b. if (x+1=3) OR (2x+2=3) then x:=x+1
c. if (2x +3=5) AND (3x +4= 7) then x= x + 1

M is a subset of the set of natural numbers. 10 elements of the set are prime numbers, and the rest are divisible by either 2, or 3, or 5. Determine the cardinality of the set if it contains: 70 numbers that are divisible by 2; 60 numbers divisible by 3; 80 divisible by 5; 98 multiples by 2 or by 3; 95 multiples by 2 or by 5; 102 multiples by 3 or by 5; 20 numbers divisible by 30
prove that AUB = AU(B\A)
The sum of the first n positive odd integers is n2.
Establish the formula for the sum of the first n positive even integers and use proof by mathematical induction to prove its correctness.
Use predicates, quantifiers, logical connectives, and mathematical operators to express the statement that “Every positive integer is the sum of the squares of four integers.
Given set A = {A, B, C, D, E, F, G, H} and B = {B, D, E, J, K}. Find for the:
1. A ∪ B
2. A ∩ B
3. A x B
4. B x A
