Multiply...
You should have an image already opened. A small window named Multiply is opened. It enables to multiply each pixel value by a constant factor (e.g. 1.25).
This function is typically useful if you want to perform an operation on an image (e.g. to correct for a flatfield). See also the other operation proposed in the menu Process/Single Image Operators.
It is not used in the actual series of EU-HOU exercises.
