What kind of math do you use every day? I certainly don’t use (or remember) half of what I learned in calculus or matrix algebra over 20 years ago. The math I need to know and use comes when I read research articles, look at students’ test results, or interpret data and graphs in political and financial news. Perhaps Arthur Benjamin’s right in his proposal to make math more meaningful in the 21st century. You can view his 3 minute TED talk below. What’s your opinion?
