    On scientific notation, am I basically just taking a number (for example) like 12000 and moving the decimal so it would look like 12.000?

    Also on 13.5, Problem 4, they say you need to see which person is right for a "planet distance problem"? How am I supposed to know who is correct?

      Which answer do you get? Did any of the people solving it have a flaw in their reasoning or a mistake in thier work?

      Well I haven't done it yet, but it doesn't make sense if I'm supposed to know who is correct because it doesn't give me an answer to actually know who is correct.

    Kinda. It should look like 1.2 then you use the exponent on the times 10 part to keep up with how many times the decimal moved.

      Scientific notation is always a number between 1 and 10 times a power of 10. 12,000 is 1.2x10^4.

      Will you show me further tomorrow at school? I sort of explain it, but I think I'll understand it better if I see it done on paper.

      I bet you are right. We will look at it together then.

      Thank you. I'll also show you the other problem tomorrow because I'm probably just over-thinking it (again). Sorry 'bout that.

    It is hard to work with scientific notation when you don't have the definition of scientific notation down. We will get it figured out. Sorry
