  - plus
```
public static Object plus(Object number,
                          int augend)
                   throws ArithmeticException
```
    Returns a number Object whose value is (number + augend), Note: This method will throw ArithmeticException if number overflows.
    
    Throws:
    
    ArithmeticException
  - minus
```
public static BigDecimal minus(Object minuend,
                               Object subtrahend)
```
    Returns the difference BigDecimal whose value is (minuend - subtrahend).
  - compare
```
public static int compare(Object obj1,
                          Object obj2)
```
    Compares two comparable objects.
    
    Returns:
    
    The value 0 if num1 is equal to the num2; a value less than 0 if the num1 is numerically less than the num2; and a value greater than 0 if the num1 is numerically greater than the num2.
    
    Throws:
    
    ClassCastException - if the compared objects are not instance of Comparable or not mutually comparable (for example, strings and integers).
  - doubleCompare
```
public static int doubleCompare(double arg1,
                                double arg2)
```
    Compares two Double numeric object.
    
    Returns:
    
    -1, 0, or 1 as this arg1 is numerically less than, equal to, or greater than arg2.
