Imagine that the number 2 button on your calculator is damaged and cannot be used. Use a flowchart to show three different ways to calculate [tex]$24 \times 12$[/tex].

There are three ways to calculate 24x12 without the '2' button: multiply by 3, break down the second number, or use reciprocals and adjust decimal places. Each method provides a correct and creative solution, exemplifying the problem-solving nature of mathematics. ;
