The study.com Math 108 Experience📖

Starting on “study.com Math 108: Discrete Mathematics” means entering a new world while the chapters are the discoveries of a new world in mathematics. Here’s a sneak peek into what you’ll be exploring and mastering:

Logic and Proofs: This is the summed-up essence where everything starts. The understanding of this topic is important because logic is the foundation of all mathematics. Here, you will get information about how to build and break arguments, signs of logical fallacies, and a truth table. You would always expect to find questions on the logical operators, truth values, and if-then statements on the exams.

Sets and Functions: Sets are the basic tools in the kit for working with discrete mathematics. Here you will look at the server concepts like unions, intersections, subsets, as well as cardinality. As for specific topics, the role of sets will be explained in detail, with functions, these objects that map elements belonging to one set to another, receiving particular attention. Basic concepts are tested in this section often so if you get a good grasp of things here then you will reap big later.

Counting Rules, Combinations, and Permutations: Have you ever thought about what is the number of permutations of elements’ sets? This section has it all, the answers are found here. It is for this reason that you will study elements such as counting principle, permutation, and combinations basics to define probability and stats. The next wonderful concept that is called ‘the pigeonhole principle’ will explain to you that it is impossible to put 11 pigeons into 10 pigeonholes without one or more of them having to share a hole.

To achieve success in the course you will be exposed to numerous subjects like graphing theory, recursion, matrices, Boolean algebra, and so on. All of these topics are not only tightly connected with discrete math, but are also widely used in computer science, cryptography, and, of course, networks. One piece of advice is to focus more on the topics such as graph theory and Boolean algebra as these notions are important in the course and are frequently used in the final proctored exam.

Key Topics to Focus On🔑

Before taking the “study.com Math 108: Discrete Mathematics final exam”, it is useful to look at topics that are regularly included in the exams and are essential to mastering the remaining content of the subject. In this article, we shall attempt to explain four general concepts by doing comparisons and then relating them to real-life scenarios so as to tally with the general perception of digesting information.

Logical Operators and Truth Tables

Concept: Logical operators (AND, OR, NOT) are the backbone of mathematical logic and are used to build truth tables, which display the output of logical expressions based on all possible input combinations.

Operator
Symbol
Example
Result
AND
T ∧ F
False
OR
T ∨ F
True
NOT
¬
¬T
False

Real-World Example: Think of a simple security system. The alarm will only go off (True) if the motion sensor is triggered (True) AND the window sensor is triggered (True). If either one is False, the alarm stays off.

Sets: Unions and Intersections

Concept: Sets are collections of distinct objects. The union of two sets includes all elements from both sets, while the intersection includes only the elements common to both.

Operator
Symbol
Definition
Example
Union
All elements from both sets
{1,2} ∪ {2,3} = {1,2,3}
Intersection
Common elements between sets
{1,2} ∩ {2,3} = {2}

Real-World Example: Imagine two circles in a Venn diagram representing students who play soccer and students who play basketball. The union represents all students who play either sport, while the intersection represents students who play both sports.

Permutations vs. Combinations

Concept: Permutations and combinations both deal with selecting items from a set. Permutations consider order, while combinations do not.

Type
Formula
Order Matters
Example
Permutation
nPr = n!/(n-r)!
Yes
Arranging 3 books on a shelf
Combination
nCr = n!/(r!(n-r)!)
No
Choosing 3 toppings for a pizza

Real-World Example: If you’re organizing books (permutations), the order matters. But if you’re choosing toppings for a pizza (combinations), the order doesn’t matter; pepperoni and mushrooms are the same as mushrooms and pepperoni.

Graph Theory: Euler and Hamilton Circuits

Concept: Graph theory studies points (vertices) connected by lines (edges). Euler circuits visit every edge exactly once, while Hamilton circuits visit every vertex exactly once.

Type
Definition
Example
Euler Circuit
Visits every edge once
Inspecting each bridge in a network
Hamilton Circuit
Visits every vertex once
Planning a sales route to each city

Real-World Example: An example of the Euler circuit problem can be the ‘Seven Bridges of Konigsberg’ whereas the creation of a route that will pass through all cities only once is an example of the Hamilton circuit problem.

So, realizing the meanings of these terms and their practical use will provide you with a firm initial basis for the solution of rather difficult problems on your discrete mathematics exam. Alright, here are some of the most common questions (and answers) that you may have if there were any confusion!

Ensure that one gets to maximize the use of the three tries that one is allowed regarding each quiz for a better score.

Q: Is it allowed to take a calculator in the final examination?

A: Yes, it is allowed to bring a non-graphing, scientific calculator during the proctored final exam. Study. com lets you use the Desmos scientific calculator in the exam, so you have no need to bring it yourself.

Q: What should I do if I fail in the final examination the first time?

A: If you failed the final exam the first time around, it is not a big deal. You can take it again within the 3-day waiting period if you do not pass it. Take this opportunity to go over subjects that may have proven hard for you, complete more mock exams, and be sure that you are ready. Just keep in mind every exam taker can take it twice only, so make it as productive as possible.
