Can anyone tell me if there's any formula for calculating |a+b| (for All a & b) or any such expression?
I went through a similar post of Janefairfax or somebody where absolute values formulas were there for some programming purposes...

Don't know where to find that post..
Plz help me!

X*Y-(X+Y)=9K
(X-1)(Y-1)=9K+1
for k=0, 1, 2 etc..
for k=0
(X-1)(Y-1)=1=1*1=-1*-1
X=2 Y=2 or X=0 Y=0 and so on....

Hi bobbym..
X*Y is NOT X^Y
its X x Y or X multiplied by Y

I'll edit my previous post to Capitalize x and y so that it looks Better. Sorry for the inconvenience caused by not using LaTex!

EEG is Electro-Encephalo-Gram/Graph and is a Scan of the ALMIGHTY BRAIN !!!

Similarly...
ECG is Electro-Cardio-Gram/Graph (related to the HEART) and EMG is Electro-Myo-Gram/Graph (related to the MUSCLES)!

All the Numbers were once invited to a party. No Sooner than Later did all the numbers Gathered Together (like Evens, Odds, Positives, Negatives etc.) Except ZERO (the Real Hero)!
He sat there (at the Origin)... In the Corner with his Beer... Watching Others!

Seeing This, the Negative Numbers thought of Including Him in their Group...
"Hey Zero! Why don't ya Join us?"

"Thanks! However..." said Zero, "... I don't have Anything to Add!"
