Did this problem give you a thrill of challenge or a shiver of dread? Some people have more number aptitude, some are more inclined to the language arts. Personally, I am oriented toward the latter, and there are at least a couple of reasons for that. One has to do with the topic of one of my prior blogs about the brain: we simply have more ability in some areas than others (though there are exceptions).
Another reason is my algebra teacher at Pershing Junior High School. I had the misfortune of getting Mrs. Hausner several years after my brother did. He was destined to become a chemistry major; my preference was Romance languages. I didn’t stand a chance of living up to her expectations of “the little sister,” and was tortured by seeing her not only for instruction, but at the beginning and end of each day as well since she was my homeroom teacher. She never got how I didn’t “get it,” and her disdain amplified my anxiety over the subject matter.
I was okay in the beginning, when we started out with something like
x=3 x+2=3+2 x+2=5
But in no time I was staring at a five term expression such as
Wait! Was that the lunch bell? I’ll solve that problem later.
But my ineptitude with figures continued to plague me. My solution to an unbalanced checkbook for more than a few months was to close the account and start over at another bank. Seriously. So, my husband has been paying our bills for almost twenty years, and the gas and electric haven’t been turned off (yet). Life is good.
Life got a little better recently. When I called my brother to ask him our teacher’s name, he mentioned a fact that either I’d never known or had forgotten: our father had enlisted a family friend to tutor him in algebra. Hmmph! But then he added this: “My nemesis was word problems. You remember, a train leaves Chicago at 8:00 a.m. traveling west at 50 mph, and another train leaves Los Angeles at 10:00 a.m. traveling east, etc.”
And the numbers versus letters train rolls on . . .
