This is a comprehensive poster on The Order of Operations. It comes with FOUR VERSIONS of the same poster formulated to PEMDAS, PEDMAS, BODMAS and BIDMAS. One thing that we find a lot of guided posters on this subject lack is an explanation of WHY there is an Order of Operations, and why it is in that order. We hope that this poster will change that, and give learners a deeper understanding of why The Order of Operations are so important as well as explaining the order itself.
