Hello Diana,
What level of operations are you interested in. Some of the old books on algorithms and calculators that came out in the late 70s and early 80s discuss some of these methods and how approximations are used to evalute log and trig functions. Is that what you are looking for?

Most calculators use decimal (BCD) arithmetic. See http://www2.hursley.ibm.com/decimal/ for a great resource on this subject. CORDIC algorithms are commonly used for transcendental functions. Googling for CORDIC should get you started.
