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.
