Original Note:
The video shows the boy using expanded form addition; a part of TERC mathematics education which has been standard in the US education system since 1990. Once children master expanded form addition they learn to simplify using the carryover method, it is not a replacement. https://pmc.ncbi.nlm.nih.gov/articles/PMC4445456/ https://investigations.terc.edu/about/history/#:~:text=There%2520have%2520been%25203%2520editions,Learn%2520More%2520%C2%BB
