Steem 101 help a noob!

What is the difference between these 2 numbers?

When it says Buy below am i buying steem for the first number or the second number?

Is the first number permanent and the second one fluctuates why?

What do these numbers mean and effectively do i want to continuously try to increase this?

Please help a noob understand.

Is this where i reinvest my steem dollars into to build my engine and upvote power? I guess I’m confused as to WHY there are 2 numbers.

Friends @socky @senseicat @davemccoy @themarkymark @kerlund74 @overkillcoin can you shed some light on this noob lol

Thanks community!
