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.
