Polish notation - A way of expressing a sequence of calculations without using parentheses to show which operation must be performed first.For example, the expression 2(4+5), which instructs the reader to add 4 + 5 and multiply by 2, would be written * 2 + 4 5 in Polish notation.To make the calculation, read from right to left until you find an operation, then perform the operation on the numbers immediately to the right of it, and continue to the next operation.So * 2 + 4 5 becomes * 2 9 and then 18;
