We give a proof of the fact that any finite integral domain is a field. An integral domain is a commutative ring which has no zero divisors.
Integral domain
https://en.wikipedia.org
In mathematics, specifically abstract algebra, an integral domain is a nonzero commutative ring in which the product of any two nonzero elements is nonzero.
Intuition for why finite integral domain is a field
https://math.stackexchange.com
If the integral domain is finite, injectivity of multiplication (by a fixed element) entails surjectivity, and thus bijectivity. That's a ...

Why is a finite integral domain always field?
https://math.stackexchange.com
Corollary Every element of a finite ring is either a unit or a zero-divisor (including 0). Therefore a finite integral domain is a field.
