Mathematical signs

Abstracts citations. Mathematical signs and common abbreviations are employed to help condense prose and a glossary of the latter is provided in each volume. Dangerous or potentially dangerous procedures are highlighted in safety notes printed in boldface type. 

Placing the concentration brackets together - without a mathematical sign between them - implies that the concentrations are to be multiplied. 

Written as Equation 4, q is the heat exchange at constant pressure and PAV is the work done. It is important to understand the significance of the mathematical signs in Equation 4, and how they relate to the change in internal energy. When q is posi-... 

It is known that any numerical number, semantic expression or mathematical sign are information. Examples of these types of information can be found in any reading of temperature or other time dependent variables describing state of the system. Information is also parameters used in the design of respective system. Also, positive or negative sign of the variable is also the information. 

A set of five d orbitals. The signs correspond to the mathematical signs of the wave functions with reference to the coordinates.

We actually try to make orbital drawings like Figure 1.5 show two things phase and probability density. The wave function itself has mathematical signs that are important... 

Figure 1,5 Representative cross-sectional drawings of atomic orbitals, which are standing waves in three dimensions. Shading indicates mathematical sign.

Figure 1.1 A p orbital on a ligand atom and a d orbital on a metal atom. The plus and minus signs refer to the mathematical signs, or phases, of the orbitals in different regions of space.

Because the different phases of the p orbital result from the different mathematical signs (+ and —) of the wave function of the electron, some chemists represent the different phases by a (-f)...
