Playing Around With a Calculator? No, Working Out
Tuesday, September 05, 2006
Just in time for school, sharp electronics has released two calculators with built-in math drill features. For younger students, the smaller EL-S50B Quiz Calculator ($12, shown here) provides practice with sets of specific math facts that you can customize, so you can work on, say, just the 7’s.The larger, gray EL-T100B Brain Exerciser ($13) doles out timed sets of random math problems to adults who want to keep their aging brains from deteriorating. The math drill feature was inspired by the Japanese neuroscientist Ryuta Kawashima, a proponent of the notion that your brain gets soft with age, unless you exercise it.
Press the Drill key to turn on the math quiz feature and you are prompted to select how many problems you want to do. Once you finish your set, you get a score; the Brain Exerciser version also includes a time and rank. There are no bells, whistles or dancing rabbits, just the satisfaction of knowing that you’ve defeated a silent drill sergeant.Both calculators are powered by a battery that can last seven years with normal use, time enough to learn your multiplication tables.
