While `3 − 4 × 5` can also be written `3 − (4 × 5)`, that means something quite different from `(3 − 4) × 5`. In reverse Polish notation, the former could be written `3 4 5 × −`, which unambiguously means `3 (4 5 ×) −` which reduces to `3 20 −`; the latter could be written `3 4 − 5 ×` (or `5 3 4 − ×`, if keeping similar formatting), which unambiguously means `(3 4 −) 5 ×`.\n\n*(from [Wikipedia](https://en.wikipedia.org/wiki/Reverse_Polish_notation))*\n\n## Installation\n\n1. Clone the project: `git clone https://github.com/Adamouization/SRPN`\n\n2. Cd into the directory and compile the files, then run the source code:\n\n```\ncd SRPN\njavac SRPN.java\njava SRPN.java\n```\n\n## Contact\n\n* email: adam@jaamour.com\n* website: www.adam.jaamour.com\n* twitter: [@Adamouization](https://twitter.com/Adamouization)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fadamouization%2Fsrpn","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fadamouization%2Fsrpn","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fadamouization%2Fsrpn/lists"}
