Scientific Notation

One can enter and compute numbers in scientific notation. For example, Avogadro's number is usually given as . To enter Avogadro's number, first type the decimal part, 6.02, then press the EE key (first column of keys, third key from the bottom, above the STO key), then type the exponent. Hence, the keystroke sequence to enter Avogadro's number is

EE

One can compute with numbers entered in scientific notation. For example,
