There's nothing new about the approach described in the Feb. 19 front-page story "Parents Rise Up Against a New Approach to Math. " I engaged in this type of mathematical analysis in 1969 as a fourth-grader, much to the dismay of my teacher. Clueless as to what to do with pictures of bundled red sticks referred to as "units," I dissected them and reordered them into a manageable array. Rounding numbers up or down to the closest ten or hundred enabled me to easily add single digits separately to get the total; I still use that technique today.

Health and Human Services (HHS) Secretary Kathleen Sebelius should be charged with voodoo accounting for her July 11 op-ed ["The truth about health-care reform"]. She wrote, "Between 2000 and 2009, the average family premium more than doubled, from $6,438 to $13,375, an annual increase of 8.1 percent. From 2009 to 2011, family premiums still rose — but at a rate 25 percent lower. That generated savings of more than $1,200 per family …. " Ms. Sebelius implies that American families pocketed $1,200 when in fact they do not. A rate increase of 8.1...

In an April 29 Metro story on meters in D.C. taxis, I found the cabdrivers' math to be as dubious as the many outrageous fares that this city's knavish cabbies have quoted me over the years. I find it hard to believe that a cabbie working "10 to 12 hours a day" could clear only $650 a week before expenses. Assuming the driver was working 11 hours a day, five days a week, that works out to about $12 an hour. I often have difficulty finding a cab near my apartment just off Logan Circle and my office about four blocks from Union Station, so the cabbie...

VARIOUS EXPLANATIONS have been advanced in the wake of publicity about high failure rates of Montgomery County high school students on final math exams. The tests don't count for much. Students just aren't trying. They are still passing the courses. Other test results are still good. None of these explanations is reassuring — particularly since the issue has persisted for years and, as The Post's Donna St. George reported, may reflect a broader problem in questionable pupil performance on final exams in other subjects.

I was disturbed by the article on Montgomery County students' chronic failures on final math exams [" Montgomery math grades, test scores aren't adding up ," front page, May 20]. But the most troubling part of the story is the county's own "math" that provides for the final exam to be "worth 25 percent of a course grade," thereby allowing students to fail the final but still pass the course. This is absurd, given that the final is the only exam that covers the entire course material, and it is no way to prepare students...
