Not at all!
An equation expresses a relationship between variables. Variables are
entities that encode values, whose magnitude can be large, or small,
or somewhere in between. To be experienced, a value must be expressed
in an experiencable quality, for example brightness (as of a light
bulb), or pitch (as of a musical note), or warmth and coldness, or
pleasure and pain. Lets pick brightness, as of a light bulb, to
represent the value of a variable.
An equation contains more than one variable, and expresses the
relationship between those variables. For example the equation
y = x2
says that whatever the value of x, y will be the square
of that value. So we need to be able to experience (in this case) two
variables simultaneously. Imagine two light bulbs. Not next to each
other, but just two individual light bulbs or points of experienced
brightness value, that are not adjacent to each other, or above or
below one another, but just experienced, independently, as two
separate experienced magnitudes. The equation y =
x2 says that whatever the value of variable
x, the other variable y will always be
equal to the square of the value of the variable x. In
other words, as we turn up the brightness of the variable x
the brightness of y will shoot up in nonlinear fashion
as determined by the equation y = x2. The
coupling between these two experienced variables, i.e. the "squared"
relationship between them, expresses the meaning of the equation which
we write in symbolic form as
y = x2.
The same thing could be done using variables expressed as musical
pitch, warmth and coldness, or pleasure and pain, etc. And the same
principle can be used to express more complex equations containing
more than two variables.
