A song about arithmetic shouldn't feel this gentle. The NHK Tokyo Children's Choir wraps numbers in warmth, and Seiji Tanaka's composition turns basic math into something that feels like being tucked in. You're not learning, you're being held.

A cheerful song about arithmetic, performed by Seiji Tanaka together with the NHK Tokyo Children's Choir, gets its own music video here. The single short piece was broadcast on NHK as part of the Minna no Uta program, pairing the choir's performance with animation built around the subject of numbers and math.
