The quiz today covered both significant digits and classifying matter, but more questions about significant digits were covered. I am fairly confident with my quiz, but I am still not completely confident with significant digits. When doing equations with both multiplication/division and addition/subtraction, I am unsure of where and when I can round in the equation and which numbers I can use to determine how many significant digits are in my answer. The classifying matter material was much easier for me to understand, and on the quiz I feel confident in those answers.
Studying over the weekend I used these links:

I have found it helpful to make a couple examples because there is only a limited number of cases where 0's are considered significant digits. If you do this you should be able to solve any significant problem thrown at you.
