Krys: That is not wrong.Write on paper:


                              73
                       --------------- = 22.7833
                       1.79*1.79




Now   73/1.79*1.79 shall say the same thing  :twisted:  
Most calculators use the Krys way though .But that's not the only correct interpretation.



Yes CTG,there are different phenotypes.Some gain weight far easier than others and have a heavier body built even without fat.But they usually gain muscle mass way faster also.

                              73
                       --------------- = 22.7833
                       1.73*1.73

WRONG!

     73
------------- = 24.3911
1.73*1.73


 :lol:

I asked for a girl in the university how heavy I look

nice pick-up line  

First she asked from me!

B?FF!

Mixed up the numbers,don't be so picky....

I believe you told he looked great, right? :wink:

He? She is a girl, I'm not gay! Btw I didn't tell her, I'm a slow strategist - time is on my side.

I don't know my weight, and I don't care :-)

I think Alain is also so thin that it's dangerous for his health.

/Mathematics lesson ON

If you mean a result as 22.xxx, then you need to write 73/(1.79*1.79).
Without "(" and ")", operations must be done in the order they are written, therefore 73/1.79*1.79 means "written on paper" (as argammon says) :
     73
  -------- * 1.79 = 73
    1.79

Mathematically, * and / must be done before + and -.
But there is no order between + and -, and no order between / and *.
This is a mathematic rule, not an interpretation. :wink:

Let me give example : 2+3*5=17, and not 25.
* has priority compared to +, so first you must calculate 3*5=15, and then calculate 15+2=17.

But 73*1.79/1.79=73/1.79*1.79=73. No priority order, operations must be done in the order they are written.

Same thing for 2+3-1=2-1+3=4. No priority order.

You need to write 73/(1.79*1.79) to have 22.xxxx has a result.

Anyway, as Argammon says, some bad calculators do not recognize the operation priorities, so 2+3*5 would give 25 as a result.
This is wrong. To have 25 as a result, you have to write (2+3)*5.

Ask your mathematics teacher if you want confirmation. :-D

Krys is right but Argie's theory is rational too.

[BonzaiJoe]

No it's not, he's just trying to escape being corrected. But I know that Argammon is a very strong mathematician and that Krys' lesson goes way below his level, so it really doesn't matter anyway. He wrote it wrong, but he knows what he's talking about.

[Renato Biker]

let a real mathematic answer it :

accurately

But there is no order between + and -, and no order between / and *.
This is a mathematic rule, not an interpretation. :wink:

this isn't a rule, it's a definition! so different...

Let me give example : 2+3*5=17, and not 25.
* has priority compared to +, so first you must calculate 3*5=15, and then calculate 15+2=17.

thus defined

But 73*1.79/1.79=73/1.79*1.79=73. No priority order, operations must be done in the order they are written.

multiplication's associative property

Same thing for 2+3-1=2-1+3=4. No priority order.

addition associative property

You need to write 73/(1.79*1.79) to have 22.xxxx has a result.

Anyway, as Argammon says, some bad calculators do not recognize the operation priorities, so 2+3*5 would give 25 as a result.

that's right, but Argammon didn't said it  :-D
just have care with your words, "operation priorities" is wrong, it's a defined operation orders, not a prioeities  :wink:

[Krys TOFF]

just have care with your words, "operation priorities" is wrong, it's a defined operation orders, not a prioeities  :wink:

Well, I didn't know how to say it in english, this is my own translation from french way to say it : "priorit? de la multiplication et de la division sur l'addition et la soustraction, sauf si l'addition et/ou la soustraction sont entre parenth?ses" = do * and / before + and - except if + and/or - are between "(" and ")".
I wrote the French sentence because I know Argammon understands French.

I know that Argammon is a very strong mathematician and that Krys' lesson goes way below his level, so it really doesn't matter anyway.

I know too that Argammon is strong in mathematics, that's why I couldn't let this small mistake uncorrected. :-D
I do not pretend to be a good mathematicians, but I know the basics of it for sure.
About the mathematic level of these "defined operation orders" (hey, see Renato : I use the proper words now :lol: ), this is for sure a low level of mathematics : my daughter is only 6 years old and she already knows it. :wink:


Edit : let's have some mathematical fun in THIS TOPIC

[CTG]

my daughter is only 6 years old and she already knows it. :wink:

Will she join Warner Bros team?  :lol:

She is not interested in racing games except when she can do funny crashes AND continue racing.
She likes Destruction Derby for example. :lol:
Crash in Stunts means race stop, she doesn't like it.

Let's go back to original topic : which sport during our freetime ?
For me, it's running, football or cycling with my children when weather is good, and sex whatever the weather ! :-D (edit : with my wife, not with my children, do not misunderstood me :wink: )
