It refers to a process of checking or verifying a property after a certain operation or transformation has been applied. The term "jäänustest" itself is Finnish, directly translating to "remainder test."
In elementary number theory, a jäänustest is commonly encountered when performing division. For instance, when dividing
More broadly, in abstract algebra, a jäänustest can be applied to various algebraic structures. For example,
