This math problem had me going for a bit. Looked at from a distance, it looked like one thing; and when I had the occasion to sit down and hash it out, it was quite another. A student submitted a Continue Reading

Pedagogical content knowledge is a type of knowledge that is unique to teachers, and is based on the manner in which teachers relate their pedagogical knowledge (what they know about teaching) to their subject matter knowledge (what they know about Continue Reading

Here I will try to explain boolean expressions. Boolean expressions are expressions that evaluate to “true” or “false”. “True” is like a value of 1 and “false” is like a value of 0 (zero). Suppose you have as your boolean Continue Reading

Arrays. I can declare an array and return an arbitrary element from it: S := {2,4,6,8,10} S[[3]] 6 I can also do the same things for an anonymous array: {2,4,6,8,10}[[3]] 6 In both cases, I request the third element of Continue Reading

Every programming language has some kind of way of doing numbers and math. Do not worry, programmers lie frequently about being math geniuses when they really arenâ€™t. If they were math geniuses, they would be doing math, not writing ads Continue Reading

Math is a mental process. Basic math techniques should be, for those that are learning basic math, of the variety that you should either be able to do in your head, writing your thoughts on paper; or learn how to Continue Reading

I have advocated Mathematica and other technologies in previous posts, but I think it is high time to advocate for doing math with the absence of technology other than an pencil and paper. I like this rather old text I Continue Reading

I have been playing with Mathematica 5, and have a big thick book on it from Wolfram and even a Schaum’s Outline on the program. All of these books touch on all of the functions of the program as though Continue Reading
