On a related note, I always hated fractions. The concept always seemed so antiquated even when I was in school. Do other countries still use or teach fractions? I?d much rather just use decimals.

I've found that people not good with fractions are typically not good with numbers in general. Fractions are important.

Good thing for me I didn?t say I wasn?t good with fractions. I just don?t like them.


And we will have to agree to disagree about the importance of fractions.

Don't like fractions, then you are not rational or is that irrational?

Fractions are not important, decimals are important. Engineers and machinists do not use fractions. Only trades where accurate measurements are not critical use them like in carpentry.

Are the engineers and machinists gonna build your house?
I would say they carry some importance.

I remember market used fraction and it was pain in the ass.


65 3/8!! Limit order at 65 7/16!! And fill!
That crap disappeared after 2000.

Division remainders are VERY important in Computer "programming". I can't tell you how I know this, but they ARE.

% (and no, that's not "percent" in this case)

Ps. There are 10 kinds of people in the world, those who understand binary and those that don't.

My father was a Tom Lehrer fan (and made me one) who was a great singing comedian from the 60s.

In the 60s a "new math" was introduced which is what I (and most of you probably) learned.

Here was Tom Lehrer's take on the old, new math.

Ps. I can remember doing base 8 math in 5th grade, which ties right into this video!

Goes to show that no matter what you learn, there will always be a "newer" math. I actually learned what Tom presents as new math. It took me a second to understand what he presented as the classic method, which really isn't different, just annotated in reverse order. I cant remember ever seeing how my Pops would have done such a problem, I think he just converted his habits to the methods I learned, but I just don't know for sure. What is being taught as new math now is quite revised, typically graphical, yet still retains the idea that it is more important to understand what you are doing that getting the right answer.
