The Scientific Notation SN-205 Calculator

The SN-205 Calculator™ is an easy to use, scientific calculator that is specifically designed for physics, mathematics and
engineering students who routinely use scientific notation or physical constants in their calculations.  It is also an excellent
teaching tool for learning and using scientific notation since it operates exclusively in scientific notation.
