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
Quote from: "Krys TOFF"Mathematically, * and / must be done before + and -.this isn't a rule, it's a definition! so different...
But there is no order between + and -, and no order between / and *.
This is a mathematic rule, not an interpretation. :wink:
Quote from: "Krys TOFF"Let me give example : 2+3*5=17, and not 25.thus defined
* has priority compared to +, so first you must calculate 3*5=15, and then calculate 15+2=17.
Quote from: "Krys TOFF"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
Quote from: "Krys TOFF"Same thing for 2+3-1=2-1+3=4. No priority order.addition associative property
Quote from: "Krys TOFF"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

Quote from: "Chulk"I think CTG is right. High 46 is doable but I don't think many if noone will do it in this race.
Quote from: "Chulk"I said I was not meaning you. I know you where blame for that as Alain did when he was the champion, so don't worry.
By the way, I find some of your jokes funny so keep on that!
