Is it posible : ||a+b||= |a| + |b| &/or

||a|+|b||=|a|+|b| ?

Is there some properties for those equations?

If you're asking if these equations are always true, then try plugging numbers in; specifically, see what happens when you plug negatives in for one or both of the variables.Is it posible : ||a+b||= |a| + |b| &/or

||a|+|b||=|a|+|b| ?

if you're asking for general identities and properties of absolute values, then you should be able to find listings online, such as

tnks so much!! It really heped me.

But actually what I'm really want to know is if the absolute-value of an equation can have a superior absolute-value. And if the answere is positive where can i find it, becuse i've been lookign after that the whole day and all I get is the usual properties and identities.

Pleas Help!!

I'm sorry, but I don't know what this means...? How does your book define a ''superior" absolute value? What do you mean when you ask "where" answers are? ("Answers" to what?)...actually what I'm really want to know is if the absolute-value of an equation can have a superior absolute-value. And if the answere is positive where can i find it....
