波兰式在计算中的价值在于它不需要使用括号，之所以如此是由于波兰式的操作符的先后顺序是明确的。 -In the general expression, the symbols are located in between the operands, while the expression in Poland, the computation involved in computing at Symbol before the object. Polish-style in the calculation of the value is that it does not require the use of brackets, the reason for this is due to Poland-based operator of the sequence is clear.
