supergems:
sometimes the pictures explain better than words ;) reference: https://en.wikipedia.org/wiki/Reverse_Polish_notation https://en.wikipedia.org/wiki/RPL_(programming_language) http://hansklav.home.xs4all.nl/rpn/ |
TIfanx1999:
Wow, that's really weird. |
Eeems:
So TI-OS doesn't follow order of operations the way we'd expect it to. :( |
Sorunome:
Why? Deviding and multiplying have same level of importance and TIOS goes from left to right rather than right to left. |
supergems:
You can use the acronym PEMDAS (Parentheses Exponents Multiplication Division Addition Subtraction) to remember order of operations: https://en.wikipedia.org/wiki/Order_of_operations. For this reason I prefer RPN calculators. ;) |
