Repeated Addition and subtraction can't make fractions grow
infinitely, only multiplication and division could.

Up to a certain limit. After you reached the limit, the fraction would
always be simplifyable.

If the input numerator and denominator have a defined limit, repeated
addition and subtraction to another fraction will also have a defined
limit.
