(id)   arithmeticAdd: 
Add the value of a given object to this object's value.  
(id)   arithmeticDivideBy: 
Divide this object's value by the value of another object.  
(id)   arithmeticModulus: 
Compute the remainder of division by the value of a given object.  
(id)   arithmeticMultiply: 
Multiply this object's value by the value of a given one.  
(id)   arithmeticNegate 
Negate the value of this object.  
(id)   arithmeticSubtract: 
Subtract the value of a given object from this object's value. 
All objects used by these methods should be forms of NSNumber, or the operations will not work as expected.
 (id) arithmeticAdd:  (id)  value 
Add the value of a given object to this object's value.
The two values are added together and a new object containing the result is returned. The result is the same as using operator +
in Standard C.
value  the value to add 
 (id) arithmeticDivideBy:  (id)  value 
Divide this object's value by the value of another object.
The result of the division is returned in a newly created object. The result is the same as using operator /
in Standard C.
value  the value by which to divide 
 (id) arithmeticModulus:  (id)  value 
Compute the remainder of division by the value of a given object.
The result is returned in a newly created object. The result is the same as using operator %
in Standard C.
value  the value by which to divide 
 (id) arithmeticMultiply:  (id)  value 
Multiply this object's value by the value of a given one.
The result of the multiplication is returned in a newly created object. The result is the same as using operator *
in Standard C.
value  the value by which to multiply 
 (id) arithmeticNegate 
Negate the value of this object.
The negated value is returned in a newly created object. The result is the same as using the unary operator 
in Standard C.
 (id) arithmeticSubtract:  (id)  value 
Subtract the value of a given object from this object's value.
The given value is subtracted and a new object containing the result is returned. The result is the same as using binary operator 
in Standard C.
value  the value to subtract
