      Characteristic (algebra)

      In mathematics, the characteristic of a ring R, often denoted char, is defined to be the smallest number of times one must add the ring's multiplicative identity element to itself to get the additive identity element ; the ring is said to have characteristic zero if this repeated sum never reaches the additive identity....
