## Math Myths

Don Cohen, AKA The Mathman, has been helping children of all ages to learn Math for 34 years. He has a CDROM book, Calculus By and For Young People, which he sells via his site.

I found these "Math Myths" from his site to be quite interesting:

- You can't take 7 from 3.
- When you multiply, the answer is bigger.
- You have to add from right to left.
- When you subtract the result is smaller.
- Fractions are small numbers.
- There's only one way to do something.
- When you add the result is bigger.
- When you divide the result is smaller.
- I can't do it unless someone tells me how to do it.
- Math is hard and only a few people can do it.
- You have to know everything about whole numbers before you can do fractions.
- You have to know algebra before you can learn about calculus.

How many of these "facts" do we take for granted, even though they're not true?

Five Vintage Math Myths:1. Math is easy! (

most likely only to math teachers and those with little knowledge of math)2. Without basic algebra, you’ll lead a life of poverty or misery! (

Why is it that most A-students eventually work for the C-students?)3. With math you can [practically or apparently] do anything! (

not if you lack intuition and imagination and common sense and ….)4. If you’re good in math you’re a logical or rational person! (

why are many Asians with good grades in math play lotteries, read “horrorscope,” consult geomancers, give offerings to idols, …?)5. Asians or Chinese are good in math! (

try asking students or even their teachers to name any dead or alive famous Chinese mathematician.)K C Yan (@MathPlus)
