I wish a math teacher would have shown me this

by Brent LeBlanc

Feb 5, 2016

I'm not sure what grade this would be appropriate (middle school possibly) but I really wish my math teacher would have exposed me to the Zipf mystery. It really would have grabbed me. I hated math when I was in school. Loved art, science and literature but disliked math. It was so boring to me. Now that I'm an adult I wish I would have taken more ...See More

I can pass a math test by guessing correctly. What does that prove? It certainly does not prove that I am mathematically gifted. Standardized exams are given to make money, to reduce the amount o...See More

Math Teach Sure..., Harpazzo. If I found the general solution to a second order ODE, it means nothing, as I could have "guessed correctly", right?

And if one is "not a good test taker", due to nerves, etc. what makes you think they can handle a complex math problem in front of twenty screaming kids?

Read the section in your text. Listen to your teacher and follow along the examples he/she works. Do problems.

No matter what anyone tells you, no one ever learned math by any other process than doing problems. There is no substitute and there is no "royal road&quo...See More

Discrete vs continuous

by EmilyPie

yesterday, 2016

Hi all! In a graph of cost of running a newspaper ad vs number of days would the points be connected? Since a portion of a day can't be purchased I would think the data is discrete and the points would not be connected?
