By giving link do we lose our PageRank?

[atakala]

Hi moz fans,
I'm asking this question because I've faced this (http://thatsit.com.au/seo/tutorials/a-simple-explanation-of-pagerank)
Till now I know that when we link to a page we **don't **lose our PageRank, we just give a PageRank  but  not to lose it . 
I mean let's say If we have a page PR 1, and  another page B which is pagerank 0,
And If we give link a to page B from page A, At the end of the iteration, we have Page A PR 1 and Page B PR 0,85.
**But **he said above the link If we give a link to a page, it would result like this.
Page A PR 0,15 and Page B PR 0,85.

Which one is true ? 
Thank you!

To be honest, I'd say that PageRank is dead. Don't even think about it. Google sometimes doesn't update PageRank for many, many months. Today, there are hundreds of other things that I'd think about before even thinking about PageRank.

Maaan, how you dare say pagerank is dead.
If you say is dead then you probably think backlinks are also dead because it's component are pagerank ( which maybe called juice) and trust.
I want to hear from you what you think about also backlinks .
Anyway, thanks for reply.
Cheers.

Here's what I mean. When you are deciding whether to do something, if your first question is, "How will this affect PageRank?" then you are asking the wrong questions.

For example: If you want to know whether to try to get a link from a website, don't worry so much about its PageRank. Ask yourself whether this is a link you would want even if Google did not exist, whether it is topically relevant to your website, whether you will get quality referral traffic, whether you will be "earning" or "building" the link, and a lot more.

All of those things matter more than a number that is increasing arbitrary and rarely updated by Google anymore. The point: Google is thinking more like a human and less like a machine. Digital marketers need to catch up (if they weren't there already).
