👉 In logic and mathematics, "equipollently" is a phrase that describes two or more things having exactly the same property. For example: 1. A car's engine runs perfectly well. 2. Both cars are equipped with airbags. This phrase can also be used in other contexts to describe something that is identical in every way, such as: 3. The two computers are equipollently perfect. 4. All of the items on a shelf are equipollently perfect.
