Intro Number Checks

This intro problem practices ISNUMBER. ISNUMBER returns TRUE when a cell contains a number and FALSE when it does not. Update the output cells so each row shows whether the value in column B is a number. See Examples

Your solution should use cell references so it updates automatically if the input cells change values.
