A meaurement; a scalar quantity.
A scalar quantity is a non-vector quantity. In a vector quantity, direction is relevant. In a scalar quantity, it is not. For example, mass (measured in kg.) is a scalar; force is usually indicated as a vector (magnitude in Newton, but the direction is also relevant).A scalar quantity is a non-vector quantity.

With great difficulty - if the given quantity is 2, for example.
any measurable quantity
An example of a quantity of time is the second. Other examples are the minute and hour. You could go on and on - day, month, year, etc.
