8+1+3=14
1+3+8=14
3+8+1=14

8+(1+3)=14
(8+1)+3=14
1+(3+8)=14
(1+3)+8=14
3+(8+1)=14
(3+8)+1=14

1 because of the associative property
(in alll addidion or all multiplication parenthesis
Do not matter)

Wait mathwiz3502, multiplication including parenthesis does matter, in that sense:

$5(8+1)$

Adsfjlahsdflkab, considering that you are new here, with one post, which is a question and not an answer to anything... let me explain a little something before you negative your way right out of this place...

No one here can possibly know what a poster does or does not already understand. Because most of the time they don't say. They post a problem. There could be 4 steps to something and they've already solved the first 3 and we'd have no clue. So we just have to start somewhere. Wondergirl started in one place; iamthetman started in a different place. Neither of them actually did or did not solve anything... they just "started" some place.

If you brought your mind-reading cap with you, we'd appreciate if you'd share it with the rest of us.
