<\/div>\n<\/a>Math functions is a topic that confuses a lot of people, but is very important.<\/p>\n
In this article I discuss a problem sent to me by a reader. He got stuck because he was not sure about function notation.<\/p>\n
[Confession time: When I was a young math student, I remember struggling with the concept of functions for a few months. Now I realize the problem was the notation<\/strong>, not with me!] <\/p>\n Check out the article: Functions<\/a><\/p>\n Here's an interesting "real life" math topic - Gini Coefficient.<\/p>\n In some countries, wealth (and income) is distributed reasonably evenly (for example, Denmark), while in others, a small group of people hold most of the money (many African and South American countries).<\/p>\n The Gini Coefficient is one way to measure income equality.<\/p>\n Some of the math concepts in this article include:<\/p>\n Here's the link: The Gini Coefficient of wealth distribution<\/a><\/p>\n (a) Anxiety affects basic counting: <\/strong>It's been known for some time that anxiety about math causes a conflict in our brains and reduces math performance. But it was thought this only affected higher-level math. <\/p>\n A new study from Canada's Waterloo University, "Mathematics Anxiety Affects Counting But Not Subitizing \t\tDuring Visual Enumeration<\/em>" shows math anxiety affects even basic counting. You can read a (simple English) summary here: <\/p>\n New Waterloo study shows math anxiety hinders basic counting<\/a><\/p>\n (b) Girls learn math anxiety from their teachers:<\/strong> A study by the University of Chicago examined 52 boys and 65 girls in elementary school classes taught by 17 different women. <\/p>\n The more math anxious the female teachers were, the more likely their female students became anxious about math.
