Poor ol’ algebra; no one ever asks, “Why do I have to learn to read?  When will I ever use this anyway?”

But almost everyone has wondered, “Why do I need to learn algebra?  When will I ever use this?”   Well, as it turns out, there actually  is a point to it.

We all know that we need to learn basic arithmetic in order to solve everyday problems.  Things like cutting a recipe in half or keeping track of our checking accounts require math.  Have you ever looked at Office Depot’s coupons?  Often times, there are two to choose from.  One is for 20% off one item, and the one gives $10 back when you spend at least $50.  I always have to stop and do the math in order to know which one gives me the best deal.

But why do we need to learn algebra?  At first, it doesn’t seem to have any point or purpose.  In pre-algebra, you are taught things like the Proper Order of Operations and the Distributive Property of Multiplication, but you aren’t always told why.  Later you are taught how to solve a quadratic equation, but again, it’s not clear why you are solving them.  It isn’t until Algebra II, that it all comes together and makes sense, but that’s a long time to wait.  That’s like spending 12 years learning how to read but waiting until you’re a senior in high school to read a book.

You see, in Algebra II you are given story problems that can only be solved by writing an algebraic equation.  Once the equation is built, you just apply all the different skills you learned in Algebra I to solve it and get your answer.

The reason you learn basic Algebra in high school isn’t just to graduate or score well on the SAT (although those are two very good reasons); it’s so when you enroll in college you already have the ability to solve algebraic equations.  Then, your instructor will teach you how to apply that knowledge to your particular field of interest.  For example, if you are studying to be a Structural Engineer, like my son did, then you will use algebra to calculate how thick a concrete foundation must be to hold up the building during extreme events.  A nurse will use algebra to calculate the proper doses of medication, and business majors will use it to solve things like compound interest and depreciation.  In fact, most college degrees require you to learn algebra; it’s what professional people use in high paying jobs.

So, the next time you hear someone ask, “Why do I need to learn Algebra?”  Tell them it’s the one skill that can make the difference between a blue collar job and a white collar job.  With algebra you can earn a college degree and become anything you want to be.  Without it, you limit your career options and possibly your full potential.  The way I see it, Algebra is as important as learning how to read.
