The very confusing HALF (basics in math)

07/17/2008 5:30 AM

Hi guys,

Sice Im just doing Insrument Datasheets today, and its so boring, although when it comes to checking....anyway, Im just browsing today here in CR4, and I've read a forum, and I've read this statement "4.5 (not four and a half)" , they are referring to age I think, then BOOM, curiosity exploded in my brain telling me that

--" four and a half is supposed to be 6 not 4.5 you so called Engineer!

hehe damn you brain!

what do you think?

a)--"one and a half is 1.5" ( which is correct)

b)--"two and a half is supposed to be 3"

when we study statement (b) what does "half" means? or "half" of what?

or isnt two is the base thats why "half is supposed to be reffered to the base "

so

=two(base) and a half(of base)

=2 and 1

=3

What do you think?

I just want to hear/read your opinions on this.

Cheers.

"Four and half", in decimal units, means four units + half a unit, period. In the same way 123.5 reads one hundred units + twenty units + 3 units + HALF a unit.

Having already answered to your basic question, let's put a more interesting issue. When you say that you read "half a book", what do you mean?

a) you read the first half of pages

b) you read one odd page every two

c) you read one odd word every two

d) none of the previous...

affectionately

Stefano

What is confusing to me is that half full is exactly the same as half empty,

Either way, you are going to have to refill the glass.

We used to use those books with carbonless multiple copies for stores requisitions. You know the sort, you write on the top white copy which stays in the book; the next sheet is yellow and you hand it over to stores; the next sheet is blue and ends up in accounts, and, the bottom copy is green and you keep it for your records. When we needed a new book I could never work out if the old one was full or empty.

Well, I have heard the expression, "I've got half a mind..", and now I know someone who actually has one!

I am lost

Are you "the glass is half full" type of person or "the glass is half empty" kind of person?

Here in Spain, even a relatively small country do things in a greater way: We don't speak about half empty/full glasses but bottles.

Personally, if I'm with a friend and he drunk the first half bottle, for me the bottle is half full. If I started drinking, then the bottle is completely empty for me....

So obviously, they're saying "Four and one half of four." Which is 4 + 4/2 = 4 + 2 = 6.

But why would they state it in such an odd way?

I know a woman with 4 and a half dozen of children, The tenth and last was the first son.

4 + 1/2 doz = 4 + 6 = 10.

So if I'm 5 1/2 feet tall, then I'm really 7 1/2 feet tall, or is that now 10 1/2... or?

If I tell a cop that I'm 1/2 sober, does this mean I'm 3/4 sober. The Judge would believe that wouldn't he?

My grandfather had a habit of adding "half again as many" to numbers to increase the number. "You have 4? Well you'll need half-again-as-many to make an even 1/2 dozen". 4 + haam (2)= 6.

I don't know where that particular bit of verbiage got started but it was confusing to an 8 year old. LOL

1.5= 1 and 1/2 units, 5.33= approx 5 and 1/3 units, etc...

Please don't change BASIC math on me now! I don't think I could stand the strain.

Does this have something to do with Roman noodles?

I not sure about Roman noodles, but it might effect my pot size if I need 4.5 bags of Raman noodles...

OK. Here's an interesting little question... The ancient Egyptians had absolutely no knowledge whatsoever of Pi, yet why does it appear so much in their architecture and building?

Hi vermin

It must have been the aliens....

Or maybe the way they laid out their measurements...cubits, palms, fingers...just lucky? Or it's those pesky aliens again....

It's because they really liked measuring large things with measuring wheels! It really seemed to work for them - perhaps their string was too stretchy. At any rate, by using measuring wheels, PI wound up in just about everything they made.

Here are a few unbiased testimonials...

Optimus, Optimus has Megatron gone and scrambled your gel circuitry? Your thinking is remiscent of my mothers and that is a very SCARY statement, very scary indeed... Go sit down and think it over, ok? 4.5 is four and a half...4 and a half of one, not 4 and a half of four (or 2). Now, I know that you are probably just having fun with this (if not, find a dr.)... Wait, on second thought, why don't we just call it 11 halves instead of 4 and a half?

No. No. No. We're talking Roman noodles! You know, the ones they used to count with? During the Roman Umpire? The guys that invented the Seesaw Salad.

"Friends, Romans, country bumpkins! Lend me your beers!!! All the alcohol is being used as fuel!"

Those guys! They counted I, II, III, IV, V, VI, VII, VIII, IX, and X = 6 = VI, so 9 is really IX -> thus IX - X = III... But they also forgot to invent zero. That was left for the Spanish in California to invent... "Zero rides again!!!"

"Ah ha!!! Was he red, like an apple or red, like a rose?!"

Nor Incas, nor Aztecs. When your landscape is almost straight up and down, there's no much use for a wheel... At least the way we think of using it.

Maybe because they did not use the latin symbols? maybe we just haven't found the hieroglyph for it yet, maybe a sandpie?
