  As mentioned earlier, a (nonzero) number raised to the 0 power is 1:
  
  This value is also obtained by the empty product convention, which may be used in every algebraic structure with a multiplication that has an identity. This way the formula
  
  also holds for n = 0 {\displaystyle n=0}.
  
  The case of 0 is controversial. In contexts where only integer powers are considered, the value 1 is generally assigned to 0 but, otherwise, the choice of whether to assign it a value and what value to assign may depend on context.
