[

Note :
The word multiplication is sometimes used in mathematics ,
particularly in multiple algebra ,
to denote any distributive operation expressed by one symbol upon any quantity or any thing expressed by another symbol .
Corresponding extensions of meaning are given to the words multiply ,
multiplier ,
multiplicand ,
and product .
Thus ,
since [
phi ](
x y ) = [
phi ]
x [
phi ]
y (
see under {
Distributive }),
where [
phi ](
x y ), [
phi ]
x ,
and [
phi ]
y indicate the results of any distributive operation represented by the symbol [
phi ]
upon x y ,
x ,
and y ,
severally ,
then because of many very useful analogies [
phi ](
x y )
is called the product of [
phi ]
and x y ,
and the operation indicated by [
phi ]
is called multiplication .
