When will you ever use algebra? 

As a math person, there is a question that I get asked incessantly.
And it’s this:

When will you ever use Algebra???
Ah, thank you Mr. Dewey!
If you are old like me, then when I say Dewey, you think of an antiquated card filing system from the library.
Different Dewey.
The one of whom I speak is the one that ruined education and is the reason you ask me this question. No one would have asked this question back when Benjamin Franklin was writing the constitution.
What is the point of learning something? Really? Ugh.
Typically I give them a brilliant, well thought out, perfectly configured explanation and then I get this response……
So I hesitate to even write this blog. But in the spirit of education…..I must.
So back to Dewey.
John Dewey single-handedly destroyed the idea that becoming an educated contributing member of society was enough of a reason to learn something. I am pretty sure he was the first person to ask, “Is this going to be on the test??” (major simplification, but seriously pretty close)
Fine. So you want to be all utilitarian on me? I’ll humor you.
Why study Algebra?
1. It pays! The top 15 (yes FIFTEEN) highest-earning college degrees all have one thing in common — math skills. That’s according to a 2009 survey from the National Association of Colleges and Employers, which tracks college graduates’ job offers.
Check out how math compares with those other majors!!
MAJOR-SALARY DIFFERENTIAL
Mathematics + 37.5%
Economics +33.5%
Chemistry +22.8%
Foreign Langs +5.1%
Poli. Sci. +4.9%
History +0.9%
Biology +0.8%
English +0%
Psychology -4.40%
And then there is this handy “job satisfaction” chart…..but who wants to be satisfied with their job? Clearly not surgeons (#156, yikes)

Why are we learning this?” you ask. How about so you can provide for your family? How about so you have a better chance at actually liking your job? Good enough reasons? Great! Are there other ways to provide for your family? Obviously yes. But when do we decide that? Second grade? Ok, you will be a realtor. No algebra for you. No. Of course not. Why limit yourself? Put in the hard work. Study like you mean it. And leave your options open. There are countless jobs that will look at your math success and be pretty impressed. Why? Because succeeding in math means that either you are pretty smart or you work really hard, or somewhere in between. Employers seem to like those qualities. There, algebra helped you.
2. Your brain needs algebra. While I will concede that you may not use “algebra” (insert Chris Farley air quotes here) in the sense that you are taking out a piece of paper and solving for x, every day, you are (hopefully) at the very least using algebra skills to make logical connections and solve problems daily. And just like any muscle….that part of your brain needs to be worked out. Would you ask a trainer at a gym “When am I ever going to need to do 50 lunges in my life?” 
No, that’s ridiculous. Of course you won’t be doing those exact movements. The point isn’t to be able to do lunges, the point is to work that muscle and get in optimum shape so that you can further your fitness goals and operate at peak physical capacity.
3. To know God and make Him known! If you are a Christian, then this alone is a reason to study math. God invented it, uses it, reveals Himself through it and on and on! Discoveries in math are so divinely designed that people once worshiped the creature rather than the creator and started worshiping numbers. On the other hand, I remember the first time I heard Chuck Missler, (mathematician/pastor) speak, it was as if I had heard the Bible in a way I never imagined possible. The marriage of mathematics and theology is nothing short of miraculous and beautiful! If you run from math, you will be missing out on knowing a part of God you can only learn about through studying that realm of His design. He is a math God people. Face it. 😉 When you study anything that He created and designed you will learn more about His principles and character and literally just be in awe! Oh yes, when you see how beautiful a proof comes together, you can’t deny the power of God! GP are you with me?
I can hear you now….
“Oh, so you think you are smarter/better/more logical than I am because you are good at math?”
Actually. Yes. That is exactly what I think.
What I mean is I just may be smarter than you in math.
And some of you are smarter/better/more knowledgeable in art/history/science/ or music. 
The reality is that learning is good for you. It makes you better. Period. Learn about something. Turn off the T.V. And pick up a book. Any book. Enrich your mind. Learn algebra. You will be better for it. Learn history. Lord knows someone needs to! Find out why the Crusades started for instance!  Learn about science. Real science. Not fake “It’s a baby if you want it to be” flat earther science. 
But for heaven’s sake, don’t ask a physical trainer, “When will I ever do lunges in real life?”
 And don’t ask a math teacher, “When will you ever use Algebra in real life.”
Because when you ask “Why did I need to learn algebra?” I would say, “Why not?” And for that matter why is no one asking “Why did I need to learn kickball?” or “Why did I need to memorize elements on the periodic table?” How many adults are using either of those skills on a daily basis?
Let’s get to the real issue.
Algebra can require a lot of practice, hard work, and firm foundation with facts.
So the real question is, “Why do I have to work hard when I don’t want to?” And this is what so many seem to struggle with these days. Why do I have to sacrifice my needs when I don’t want to? Why do I have to be kind when I don’t want to? Why do I have to humble myself when I don’t want to? Life is full of opportunities to work hard and show diligence in a challenging situation.
How will you respond?
Algebra teaches you to follow laws and absolute truths, even if you don’t fully understand them. Learning Algebra increases your ability to think logically and solve problems. This is proven. (see what I did there? Proof? Oh math humor!)
When people say, “I never use Algebra” what they are saying is:
I never find missing information.”
I never work through a problem logically”
I never follow rules and directions to complete a task.”
I never apply known information to find an unknown answer.”
Those are all skills sharpened and taught in algebra. For some people these skills come more naturally than others, but regardless of whether they are learned or not you are still using principles of algebra.
I know what else you are going to say:
“I am logical and smart, and I stink at algebra.”
 Ok. Let’s say that is true. 
I could say, “I am fit and in shape and I never do lunges.” Well, first of all, the premise may be debatable. Second of all, regardless of how smart or in shape I am, when you don’t exercise (brain or body) you will be less than what you could be.
This is just like when people say, “I don’t follow God, but I am a kind and loving person.”
The reality is that you are following the principles God has established whether you acknowledge Him or not. Similarly, you are applying the principles found in Algebra whether you acknowledge it or not.
So for this momentous occasion, this once in a life time “Pi Day” (3/14/15) that we are all celebrating……it is my one wish that people all over the world would stop asking the question…..at least for one day 🙂

Does the Bible need an update?

 Holy_Bible_answer_7_xlarge

 

“The book is wrong” my math student proclaimed indignantly from the back of the room.

And just how did he come to this conclusion?

Well, the answer in the back of the book didn’t match his answer so of course the book was wrong.

Was it? No. Most likely he had made an error. Maybe it was a computational error, maybe he skipped a crucial step, or maybe he used a faulty method leading to a wrong conclusion.   But rather than redo the problem, ask someone who knew more, or dig deeper into the concepts, it was just easier to decide that the book needed to change. It needs an update.  While it’s possible that there may have been a typo in this math book regarding an inconsequential number, the fact remains that the essentials of the book, the math theorems, the math definitions have not changed.

We are living in a time where I hear this proclamation all the time.

The Book is wrong. It needs an update. The answers don’t match my feelings. But the book they speak of isn’t just a three year old math book put together by some pretty smart math guys. The Book they accuse of being outdated is the Word of God that has been proven true for over 2000 years.

Let’s go back to the math book for a minute. Imagine this scene with me. My student, Tony, raises his hand in Algebra class and with certainty declares, “the book is wrong.” Compliantly,  I check it out, look at his work, and point out his procedural error and try to move on with class. “No,” he insists, the book is wrong.  I like my way better, it makes sense to me.” Assuming he really wants truth, I call in the head of the math department to try to further explain these concepts to him, but to no avail.
“No,” Tony continues. “I want to divide one side of the equation by 2 and divide the other side by 4.  I know your outdated theorems say that I have to divide both sides by the same number to keep the equation equal, but that was then, this is now. It is equal because I say it is equal. I am going to divide only one side of the equation by 2 and I declare that both sides are equal. Those math laws work for you, but they don’t apply to me.”

Do you see how ridiculous it is for an algebra student to debate the veracity of math laws with a someone who has studied math and all of the complexities of math for longer then said student has been alive?  No, these laws are not up for debate. They have already been vetted with rigorous proofs for hundreds of years by the greatest math minds of our time.

Likewise, the Bible has been proven true. It’s standards have been set for thousands of years.  So if you want to start changing laws and standards established by God, and proven throughout history, you better have more sound reasoning than “it works for me.”
 
Psalm 119:160 The sum of your word is truth, and every one of your righteous rules endures forever.
