Hi.

I have signed up for the introduction to astronomy course at coursera.

https://www.coursera.org/course/introastro

Video describing course http://youtu.be/lOmXPQtQzC8

In the suggested background section it suggests "A familiarity with the rudiments of high-school algebra " . Unfortunately my schooling did not involve algebra at all. Im trying to remedy this in the 3 months i have before the course starts by using Khan Academy to bring my math skills up to speed. Im already starting to do decimal division and multiplication and am just about to start exponents, which is the first example of math needed. Im finding this stuff is mostly review so far thankfully. But the formula example in the second part looks more advanced and unfortunately i have no memories to pull from.

If you could please look at the attachment image and look at example 3 which starts with the words " A familiarity with the rudiments of high-school algebra, the ability to solve an equation like...." and let me know how deep this is i would be grateful. I am worried that 3 months might not be enough to get up to that level. I am wondering what the path is from finding composite and primes, multiplication and division of decimal numbers, basics on exponents, positive and negative numbers, which is all arithmetic and pre-algebra according to Khan and the math needed for this course. How far do i have to go?

I have also signed up for a Introduction to Mathematical Thinking course at coursea as prep for the Astronomy Class. This course starts sep 17th and i figure that even if i cant pass it, learning how to think about math in a more advanced way, will be nothing but a benefit.

Hope im not trying to reach too far too fast.

Thank you for any responses.
