This week my ah-ha moment was when I learned about negative exponents on numbers. I thought it was going to be very difficult to do but then I learned that all you need to do is the reciprocal of the number because when you have a negative from the top of a fraction, you move it to the bottom and if you have a negative exponent on the bottom you move it to the top, and if there is no fraction shown you make the denominator 1 and then flip it.
