“Math: Not Even Once” or “Things You Really Can’t Do in Math… Even Once!” December 26, 2013

“This is your worst subject?” my business professor asked, nodding towards the math classroom.

I nodded rather sheepishly, a bit glad that she didn’t know about my math-centric business background.

“Then I’m impressed,” she replied.  “I’ve been looking over your test while we talked and I could be wrong, but I think you got 100%!”

I felt something inside of me start to glow.  It hadn’t been an easy journey, yet I had to admit that maybe math wasn’t my worst subject anymore.

Unfortunately, this left me with a conundrum.  For weeks, I’d been repeating the slogan, “Math: not even once.”  The phrase was too good to give up, so surely there had to be another way to apply it.  And I found just that in the work of Pierre de Fermat (1601?-1665), a French lawyer who appears to have engaged in mathematical exercises “just for the fun of it”.  His hobby led to some incredible breakthroughs in the field of mathematics (proof that “amateur” is not synonymous with “inept”) and is best known for his contributions to calculus.

According to Fermat, there are two mathematical operations which simply cannot be done… even once.  The first is separating a single cube into two cubes.  Go ahead.  Try it.  It really is impossible!  The second is separating, “a fourth power into two fourth powers, or in general, any power higher than the second, into two like powers.”  (I’d challenge you to try this too, but despite the fact that I do find some math to be enjoyable, I’m not quite ready to tackle this one!)[1]

So what did I learn from all of this?  Quite simply that sometimes in life, what we tell ourselves has more to do with our perceptions of reality than what actually is.  And many times, it’s our ability to question these perceptions (and carefully weigh their alternatives) which leads to our failure or success.  While it’s unlikely that I’ll ever have the computational genius of Fermat, one thing is certain: math and I are not the enemies I thought we were.


[1] While I’d love to take credit for discovering this amazing connection between the popular “Meth: Not Even Once” commercial and Fermi’s last theorem, I have to give credit to the folks on zazzle.com where you can purchase a t-shirt with the theorem in Latin.

“Math: Not Even Once” or “Life as a Professional Shopper” December 19, 2013

I admit that I didn’t view buying for a corporation as a “numbers job” per se.  In fact, when people asked what I did for a living, I usually responded that I was a professional shopper.  I spent my days browsing catalogs, reviewing trends and sales figures, and negotiating better pricing and payment terms for the products our stores required.  There were trade shows throughout the fall and I found myself in an assortment of locations from Las Vegas to Philadelphia as I scouted for the best deals and the most innovative new products.  To be honest, the job was fun.  It was as much art as science and the math behind it was repetitive and simple.  Still, I continued to repeat the phrase I’d learned in second grade: “I hate math!”

This strange tug-of-war between what I actually did for a living and what I thought I didn’t enjoy continued until the recession hit.  My job was safe through the first part of the downturn and then, in an effort to save money, the company was reorganized and I was cut from the staff.  Individual department managers were eventually to do their own purchasing.  I was handed a severance package and an excellent letter of recommendation and shown the door.

Over the next few months, I searched for employment and, finding it scarce, decided to go back to school.  I would get an degree in Business Marketing and Management (I had, after all, enjoyed the work I’d been doing).  Unfortunately, the pursuit also meant that I had to take a class entitled “Practical Business Math Procedures”.  Muttering the words, “I hate math”, I picked up my book from the campus store and set to work.

Several weeks into the course, it was becoming apparent that I was actually doing quite well.  Thanks to Mom’s hard work and the time I’d spent as a buyer, I was already familiar with most of the concepts being studied.  And the unfamiliar ones only built upon those.  In fact, I found myself relishing problems like:

“If Henry’s Baked Goods makes 3 dozen doughnuts every morning at a cost of 17 cents each and a half-dozen of those doughnuts will spoil before the day is over, how much should he sell them for in order to achieve a 40% markup on cost?”

Or

“Danny’s Outfitters in Boston bought climbing gear for resale.  They purchased 10 ropes at $500, 14 helmets at $25, and 2 dozen chalk balls at 93 cents each.  FOB SanDiego $400.  They were given a discount of 10/5/2 and terms of 2/10 n/30.  Presuming they paid within the discount period, how much did Danny’s Outfitters pay for the gear?”

It wasn’t until I started looking forward to figuring out payroll taxes and effective interest on treasury bills, however, that I began to question my mantra.  Did I really hate math or was it just that I hadn’t enjoyed struggling with it in the beginning?  Was it possible that I only hated numbers because I’d spent so many years telling myself that I did?  (To Be Continued…)
