====Powers of zero====
For a positive exponent {{math|''n'' > 0}}, the {{mvar|n}}th power of zero is zero: {{math|1=0<sup>''n''</sup> = 0}}. For a negative exponent, <math>0^{-n}=1/0^n=1/0</math> is undefined.

In some contexts (e.g., [[combinatorics]]), the expression [[zero to the power of zero|{{math|0<sup>0</sup>}}]] is defined to be equal to <math>1</math>; in others (e.g., [[Mathematical analysis|analysis]]), it is often undefined.
