@ -2147,27 +2147,27 @@ make one large Square, with a side of three inches, and I had hence proved to
|

my little Grandson that --- though it was impossible for us to see the inside of
|
||||
the Square --- yet we might ascertain the number of square inches in a Square by
|
||||
simply squaring the number of inches in the side: ``and thus,'' said I, ``we know
|
||||
that three-to-the-second, or nine, represents the number of square inches in a
|
||||
Square whose side is three inches long.''
|
||||
that $ 3^2 $, or 9, represents the number of square inches in a
|
||||
Square whose side is 3 inches long.''
|

|

The little Hexagon meditated on this a while and then said to me; ``But you
|
||||
have been teaching me to raise numbers to the third power: I suppose
|
||||
three-to-the-third must mean something in Geometry; what does it mean?''
|
||||
$ 3^3 $ must mean something in Geometry; what does it mean?''
|
||||
``Nothing at all,'' replied I, ``not at least in Geometry; for Geometry has only
|
||||
Two Dimensions.'' And then I began to shew the boy how a Point by moving
|
||||
through a length of three inches makes a Line of three inches, which may be
|
||||
represented by three; and how a Line of three inches, moving parallel to
|
||||
represented by 3; and how a Line of three inches, moving parallel to
|
||||
itself through a length of three inches, makes a Square of three inches every
|
||||
way, which may be represented by three-to-the-second.
|
||||
way, which may be represented by $ 3^2 $.
|
||||
|
||||
Upon this, my Grandson, again returning to his former suggestion, took me up
|
||||
rather suddenly and exclaimed, ``Well, then, if a Point by moving three inches,
|
||||
makes a Line of three inches represented by three; and if a straight Line of
|
||||
makes a Line of three inches represented by 3; and if a straight Line of
|
||||
three inches, moving parallel to itself, makes a Square of three inches every
|
||||
way, represented by three-to-the-second; it must be that a Square of three
|
||||
way, represented by $ 3^2 $; it must be that a Square of three
|
||||
inches every way, moving somehow parallel to itself (but I don't see how) must
|
||||
make Something else (but I don't see what) of three inches every way --- and
|
||||
this must be represented by three-to-the-third.''
|
||||
this must be represented by $ 3^3 $.''
|
||||
|
||||
``Go to bed,'' said I, a little ruffled by this interruption: ``if you would talk
|
||||
less nonsense, you would remember more sense.''
