adj. Adjective.
v. Verb.
q.v. "Which see.'
/ A mark of division, as A/B, meaning "A divided by B."
./. The same as above.
[Transcriber's note: / will be substituted for this divide symbol.]
= A mark of equality, meaning "is equal to."
X A mark of multiplication, meaning "multiplied by."
[Transcriber's note: * will be substituted for this divide symbol.]
Fractional exponents indicate the roots expressed by their denominators
and the powers expressed by their numerators. Thus, A^1/2 means the
"square root of A;" A^1/3 means the "cube root of A;" B^3/2 means the
"square root of the cube or third power of B."
The use of powers of ten, as 10^10, 10^11, as multipliers, will be found
explained at length in the definition "Ten, Powers of."

Absolute. adj.
In quantities it may be defined as referring to fixed units of quantity,
and it is opposed to "relative," which merely refers to the relation of
several things to each other. Thus the relative resistance of one wire
may be n times that of another; its absolute resistance might be 5 ohms,
when the absolute resistance of the second wire would be 5/n ohms. A
galvanometer gives absolute readings if it is graduated to read directly
amperes or volts; if not so graduated, it may by "calibration" q. v. be
made to do practically the same thing.
