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.
| operator | description |

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.
