    Pre-Algebra 2-9 Scientific Notation An ordinary penny contains about  20,000,000,000,000,000,000,000 atoms. The  average size of an atom is about 0.00000003  centimeters across. The length of these numbers in  standard notation makes them  awkward to work with. Scientific notation   is a shorthand way of writing  such numbers.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
