Donkey Kong Jr. Math is an edutainment spinoff of Donkey Kong Jr. where players get to solve math problems with Donkey Kong Jr. There are three modes: "Calculate A", where two players compete to create a sum number that equals the number Donkey Kong holds up using numbers on vines and arithmetic operations laying around; "Calculate B", which is a harder version of "Calculate A"; and "+−×÷ Exercise", where players can brush up on their basic math skills.

In this run, Cephla plays "Calculate B" and manipulates the RNG in order to spawn numbers and operations in the right places so that each round can be won as quickly as possible. As only one player can win each round, the second player immediately dies to save time.

Watch this run being played back on a real console.
