    *returns the average(arithmetic mean) of its arguments , which can be in numbers or names , arrays or references that contain numbers.

    2.DDM=DBB(cost;salvage;life;period;factor)
    *returns the depreciation of an asset for specified period using the double-declining balance method

    - to checka whether all arguments are TRUE and return TRUE if all arguments are TRUE
    3. for Statistical formula in MIN(number1;number2:...)
    - to returns the smallest number in a set of values.Ignores logical values and text.
