Abstract
�/p>
Nowadays,
with
the
continuous
improvement
of
people's
living,
electronic
products
have
already
walked
into
each
and
every
family,
whether
life
or
learning,
or
entertainment
and
recreation
almost
everything
cannot
do
without
the
electronic
products,
computing
capability
of
large
and
complex
is
the
human
brain
are
not
competent,
and
relatively easy to go wrong. The calculator as a fast general-purpose computing tools are easy
to use, but it is still in development, later will appear a calculator function more powerful, so
this design is to design based on 51 single chip computer, the realization of the basic functions
of add, subtract, multiply and divide, uses LCD to display the results of data.
