To make a cardboard calculator, cut a rectangular piece of cardboard for the base, and then create smaller rectangles for the buttons and display. Use a marker to label the buttons with numbers and operations. You can create a simple mechanism by folding cardboard strips to act as levers for buttons and connecting them to a paper display that shows the output. Finally, assemble the parts using glue or tape, ensuring everything is securely attached.
