I can add and subtract negative numbers.     I thought that this was easy.

I can multiply and divide negative numbers.     I thought this was slightly harder than adding and subtracting negative numbers but not that much harder.

I can simplify expressions using exponents.     I thought this was really complicated until I got the hang of it then it was actually really easy.

I think that I at least should get a B in math because got at least a B on every test so this is the letter grade I think I deserve.
