Order of the operations
The order of the operations recommends that the mathematical operations are not carried out in the writing order but priority of treatment given to each type of operation.
The priority is thus defined:
- brackets,
- exhibitors,
- quotients (multiplication and division),
- sums (addition and subtraction).
A scientific Calculatrice takes into account this order of the operations.
In data-processing Programming, one speaks about precedence (or fixity in Haskell) over the operators. Some data-processing Languages as the Langage C have only operators whose names are preset. Of another languages like Haskell or Perl 6 makes it possible to the programmer to define new operators over which they must also specify precedence.
