What is the speed limit??? I don't have time to solve and drive. It is hard enough going the speed limit now you have to figure it out too? What if you solve it wrong? Sign is cruel. What if they actually did this? All the dumb people who never took algebra would be getting a lot of tickets. The answer is 45 mph. I'm smart. Whether I could drive that speed that's another story.
I don't tend to like children very much. Actually, what I should say is I don't tend to like being around children very much because I object to the results of most people's parenting. Whatever the case, I adore intelligent children who use creative problem-solving techniques.
