Trivia Thursday MATHEMATICS

It is once again Trivia Thursday. I will post a new set of trivia questions every Thursday. The rules are simple. Please put your answers in the comments section of the post and I will reveal the answers next week or whenever I feel like it. No Cheating! I trust that all of you will all use the honor system? That means you will not use Google, (or any other internet searches) or mooch off other peoples answers. Cheating is BAD. If your employer has somehow made it impossible for you to post comments (bastards), you may also email your answers to me at MCnMarty@hotmail.com.

Marty had to pass the Praxis I exam for school in order to enroll in any of his remaining classes, including student teaching. The Praxis is a basic skills test in reading, math and writing that measures the academic proficiencies of students trying to seek teacher certifications. Marty was not overly concerned with the reading and writing sections, but we had to study for a couple of weeks to brush him up on the math skills he had not looked at or practiced in almost 20 years. My favorite was when I said something about finding the common denominator and he looked at me quizzically and mouthed the word "denominator". I was suddenly nervous about his success on the test. He took six practice tests and with my awesome tutelage, he scored above and beyond the passing grade. Through this, we only threatened to maim each other about four times. Not too bad. It was during this time that I uttered our new favorite phrase in our house, "I will roll your f-ing head across this floor." I think I said it all serious at the time, but we both started cracking up and repeat it quite often now. So, here are 20 questions that we did to practice for the Praxis. Let's see how you do! No calculators are allowed during the Praxis, but I will allow them during Trivia Thursday. Good luck.
