The first step in the algorithm to evaluate an arithmetic expression is to transform the expression from infix form to postfix form, also known as Reverse Polish Notation. This conversion is necessary to simplify the evaluation process and avoid the need for parentheses and operator precedence rules. Once the expression is in postfix form, it can be easily evaluated by iterating through the operands and operators from left to right.
