https://steemit.com/faq.html#What_is_delegated_STEEM_Power

no need to apologize for asking, Im trying to help people.
that is the link for the article about it under the FAQ section. it will explain it all. On your homepage ,to the right of the post link is the circle with your pic in it that has the links for blog wallet and all that, to the right of that is three horizontal lines. click on that and you will see links to FAQ, read them all, the white paper and blue paper. these should explain everything.

Ill give you the quick breakdown. If you write a post the default setting is 50%50%. that means if it makes $100, $50 goes to your steem power and $50 goes to your spendable SBD account. You can buy Steem and SBD (steem backed dollars) and use them to power up by transferring them to your steem power. Your steam power is essentially the number in parenthesis after your name. you Irinatsvetkova , are a 27. I am a 53. Your full vote is worth probably 4cents, mine is about 12cents. when you write a post, before you actually popst it, there is an option at the bottom right to select how much of your proceeds you want to go to steem power or steem dollars. default setting is 50/50. you make steem power by producing good content that people upvote and moving your proceeds to steem power, you can do this under the wallet settings.

please do yourself a HUGE favor and read all the FAQ sections, the white paper and the bluepaper. If you need any links, let me know and ill help however i can. The more people that succeed on steemit, the more Steemit succeeds.
