Letter: Math problems


In the Sept. 4 “The Readers always write …” section the Courier editor took issue with the column titled “Math Problems?” and I believe needs to issue a correction to that comment. A simple example to illustrate my point: If there were 100 first-year teachers and 100 second-year teachers, then losing 24 percent first-year teachers would be 24 persons and 20 percent of the second-year teachers would be 20, thus resulting in a total of 44 teachers. However, there are 100 first-year and 100 second-year teachers, for a total of 200 teachers. Thus, losing 44 out of 200 is a 22 percent loss of personnel, not 44 percent. The actual percent value will vary depending on the size of the size of the assumed number of first- and second-year teachers, but cannot reach 44 percent.
