******** Appendix ******** .. _section-precedence: Arithmetical binary operator precedence ======================================= What is ``3^2*4 + 2%5``? The value (38) is determined by this "operator precedence table". The table below is based on the table in § 5.14 of the *Python Language Reference Manual* by G. Rossum and F. Drake. the operations are listed here in increasing order of precedence. ========================== ================= Operators Description ========================== ================= or boolean or and boolean and not boolean not in, not in membership is, is not identity test >, <=, >, >=, ==, !=, <> comparison +, - addition, subtraction \*, /, % multiplication, division, remainder \*\*, ^ exponentiation ========================== ================= Therefore, to compute ``3^2*4 + 2%5``, Sage brackets the computation this way: ``((3^2)*4) + (2%5)``. Thus, first compute ``3^2``, which is ``9``, then compute both ``(3^2)*4`` and ``2%5``, and finally add these.
