a split screen comparing two methods of multiplying 26 by 86 on green chalkboards. On the left, labeled "High school," a person uses the standard algorithm, writing partial products and adding them to get 2236. On the right, labeled "University," a person uses a lattice method, also arriving at 2236. The person on the right completes the calculation faster, as indicated by the timer, and smiles at the end.
