5.  Arithmetic OperatorsArithmetic Operators
• AdditionAddition c = a + bc = a + b
• SubtractionSubtraction c = a - bc = a - b
• MultiplicationMultiplication c = a * bc = a * b
• DivisionDivision c = a / bc = a / b
• RemainderRemainder c = a % bc = a % b

8.  Logical operatorsLogical operators

Logical operators are used to combineLogical operators are used to combine
two or more relations. The logicaltwo or more relations. The logical
operators are called Boolean operatorsoperators are called Boolean operators
because the tests between values arebecause the tests between values are
reduced to either true or false.reduced to either true or false.
