1.create an empty stack to hold operands

2.if the token is an operand,push it onto stack

if the token is an operator, then pop the stack to get operand1, and pop the stack again to get operand2

perform 0operand2 0perator 0perand1

push the result back on the stack

3.after all input has been processed, the stack should contain only 1 valuein in it -the result of evaluating the expression
