Łukasiewicz notation

Łukasiewicz notation, or Polish notation, is a way of writing mathematical expressions without needing parentheses to define order. In this notation, the operator (like + or -) comes before its operands (the numbers being operated on). For example, instead of writing "3 + 4", you would write "+ 3 4". This format eliminates ambiguity about which operation to perform first, making it useful in computer science and logic. It simplifies the evaluation of expressions, as it allows computers to process calculations more efficiently without needing to figure out the order of operations.
