How can I make a calculator out of cardboard?
assistant
To make a calculator out of cardboard, you'll need to gather the necessary tools and materials, such as scissors, ruler, pencil, glue, cardboard, and calculator buttons. Begin by sketching out the design of the calculator on the cardboard. Decide on the size, shape, and location of the buttons. Once the design has been finalized, cut the pieces out, following the outline of the sketch. Apply glue where necessary to attach the pieces together and the press the calculator buttons onto the desired locations. Allow the glue to dry and then your calculator made of cardboard is ready to use.
