I’m sure all my readers have spent the week wondering about my dad and the teacher’s math book. It happened when my dad was in high school, maybe a junior or senior. It seems that this particular example of a teacher’s edition for his math class had incorrect answers in the back. The teacher, however, did not realize that they were wrong.
Now you’re probably wondering how a math teacher could not be aware that the answers provided in his book were incorrect. I suspect the poor man was teaching in a field for which he was not prepared. I would say “certified” but we’re talking about the late 1930s, when the only requirement for teaching in a small school was that you be breathing. So, I have a certain amount of sympathy for the pedagogue.
