Methods Of Proof for Mathematical Equations
Can you give a direct proof and an indirect proof of the following?
If x is any odd integer and if y is any odd integer, then xy is an odd integer.
College level proof before real analysis. Please give formal proof. Please explain each step of your solution.
Prove that (n + 1)!>2^(n+3) for n>=3 Hint: try using mathematical induction.

Haase Diagrams and Partial Ordering Relations - Consider the following Hasse diagram of a partial ordering relation R on a set A:
(a) List the ordered pairs that belong to the relation.
(b) Find the (boolean) matrix of the relation.
See attached file for full problem description.
Basic Matrix Laws - Let A and B be arbitrary n x n matrices whose entries are real numbers.
Use basic matrix laws only to expand (A + B)². Explain all steps.
Hint: Use the distributive laws.
Row Equivalent Matrices and Systems of Equations - Determine the solutions of the system of equations whose matrix is row-equivalent to:
Give three examples of the solutions.
Verify that your solutions satisfy the original system of equations.
Show work.
Binomial theorem and expanding a polynomial - Use the Binomial Theorem to write the expansion of (x + y)^6
Rule of Products - A bit string is a string of bits (0’s and 1’s).
The length of a bit string is the number of bits in the string.
An example, of a bit string of length four is 0010.
An example, of a bit string of length five is 11010.
Use the Rule of Products to determine the following:
(a) How many bit strings are there of length eight? Explain.
(b) How many bit strings are ther...
