Generally I agree with you but there are exceptions. My fifth grade grandson can do all sort of math in his head and simple algebra when I pose simple, practical problems like time/distance or miles/gallon.

That said he truly is a very intelligent kid. Now if I could just get him to do something besides videogame thumb exercise, he might have a chance to make something of himself.
