The keyboard comprises a mathematical function key and an arrow key. When the mathematical function key is pressed, the processor causes the display to display a sequence of math functions or math menu choices upon a user repeatedly pressing the arrow key. For each math function displayed on the display, the processor concurrently also causes the result of the math function to be displayed without the user pressing another key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Math menu user interface on a calculator","description":"A system comprises a processor and a keyboard coupled to the processor.
