welcome to chem 20
This course introduces fundamental theory and principles of chemistry applied to inorganic, organic, and biological chemistry. Atomic and molecular structure, chemical and physical changes, gases, solutions and colloids, nomenclature, equations and calculations will be emphasized.

In Chemistry we use calculators all the time, so get a calculator that you feel comfortable with that is also affordable. The calculator that I recommend if you don't have one already, is the Sharp EL-506W scientific calculator. It is very cheap (about $10.00) has so many useful functions for the price (my favorite is the quadratic equation solver). It's available at Fry's Electronics and many other places.
