               MACHINES


                 We use machines in our daily routines such as to clean, move, create, repair, relax, have
                   fun, and accomplish work. For example, we use a calculator to perform calculations, an
                   electric iron to iron our clothes, an electric toaster to toast bread, a washing machine to
                   wash our clothes, etc.
