The calculator performs the normal functions of a scientific calculator, and can also calculate atomic mass and molecular mass. This enables the molecular formula of a molecule to be incorporated into an equation for calculation. All calculations performed by the calculator are recorded in a note pad area for cutting and pasting elsewhere. The calculator also has a text pad area where a longer calculation can be prepared before cutting and pasting into the calculator. Drop down lists can be used to write information into the text pad area. The calculator includes the following: - A list of over 500 common compounds with their molecular formula All elements with their atomic number, element name and symbol. A list of over 100 constants. A triangle calculator A set of vector addition calculators. An extensive measurement converter. A quadratic equation calculator.
