This week I learned about the negative and positive exponent laws. For example, I learned that if you get 6 to the power of -1 that would be considered as if you were looking at 1/6, or if you get 10 to the power of -1 that would be considered as if you were looking at 1/10
this helps because for me visualizing something is a lot easier of a question than if I have to do the math. this helps a lot because it makes it easy to calculate numbers to negative powers
