public ArithmeticExpression10(Expression p0,
                              int operator,
                              Expression p1)
```
    Create an arithmetic expression to be evaluated in XPath 1.0 mode
    
    Parameters:
    
    p0 - the first operand
    
    operator - the operator, for example Token.PLUS
    
    p1 - the second operand
- Method Detail
  - typeCheck
```
public Expression typeCheck(ExpressionVisitor visitor,
                            ContextItemStaticInfo contextInfo)
                     throws XPathException
```
    Type-check the expression statically. We try to work out which particular arithmetic function to use if the types of operands are known an compile time.
    
    Overrides:
    
    typeCheck in class ArithmeticExpression
    
    Parameters:
    
    visitor - an expression visitor
    
    contextInfo - Information available statically about the context item: whether it is (possibly) absent; its static type; its streaming posture.
    
    Returns:
    
    the original expression, rewritten to perform necessary run-time type checks, and to perform other type-related optimizations
    
    Throws:
    
    XPathException - if an error is discovered during this phase (typically a type error)
  - setCalculator
```
public void setCalculator(Calculator calc)
```
    Set the calculator externally (used when reconstructing the expression tree)
    
    Overrides:
    
    setCalculator in class ArithmeticExpression
    
    Parameters:
    
    calc - the calculator to be used
  - getItemType
```
public PlainType getItemType()
```
    Determine the data type of the expression, if this is known statically
    
    Overrides:
    
    getItemType in class ArithmeticExpression
    
    Returns:
    
    the atomic type of the result of this arithmetic expression
  - copy
```
public Expression copy(RebindingMap rebindings)
```
    Copy an expression. This makes a deep copy.
    
    Overrides:
    
    copy in class ArithmeticExpression
    
    Parameters:
    
    rebindings - variables that must be re-bound
    
    Returns:
    
    the copy of the original expression
  - tag
```
protected java.lang.String tag()
```
    Description copied from class: BinaryExpression
    
    Get the element name used to identify this expression in exported expression format
    
    Overrides:
    
    tag in class ArithmeticExpression
    
    Returns:
    
    the element name used to identify this expression
  - explainExtraAttributes
```
protected void explainExtraAttributes(ExpressionPresenter out)
```
    Description copied from class: BinaryExpression
    
    Add subclass-specific attributes to the expression tree explanation. Default implementation does nothing; this is provided for subclasses to override.
    
    Overrides:
    
    explainExtraAttributes in class ArithmeticExpression
    
    Parameters:
    
    out - the output destination for the displayed expression tree
  - evaluateItem
```
public AtomicValue evaluateItem(XPathContext context)
                         throws XPathException
```
    Evaluate the expression.
    
    Overrides:
    
    evaluateItem in class ArithmeticExpression
    
    Parameters:
    
    context - The context in which the expression is to be evaluated
    
    Returns:
    
    the node or atomic value that results from evaluating the expression; or null to indicate that the result is an empty sequence
    
    Throws:
    
    XPathException - if any dynamic error occurs evaluating the expression
  - call
```
public AtomicValue call(XPathContext context,
                        Sequence[] arguments)
                 throws XPathException
```
    Evaluate the expression
    
    Specified by:
    
    call in interface Callable
    
    Parameters:
    
    context - the dynamic evaluation context
    
    arguments - the values of the arguments, supplied as SequenceIterators
    
    Returns:
    
    the result of the evaluation, in the form of a SequenceIterator
    
    Throws:
    
    XPathException - if a dynamic error occurs during the evaluation of the expression
