indices
Pronunciation: [ˈɪn.dɪ.seɪz]

(noun) indices are the small numbers written above and to the right of a number. They tell you how many times to multiply that number by itself, like in 2² which means 2 times 2.
Example
In math class, we learned that 3² equals 9, because 3 is multiplied by itself 2 times.
