If a and b are non-zero elements of R such that ab=0, then aandb are both called zero divisors. If R is non-trivial and has no zero divisors, then it is called an integral domain. Note that if a is a unit in R, it cannot be a zero divisor (if ab=0, then multiplying both sides of this equation by a⁻¹ yields b=0.
