Kobe University and Doshisha University research group found out many engineers at major companies can not solve a fundamental mathematical equation used for junior high school entrance examination tests in Japan.

In the 1980’s, the percentage of people that got the answer correctly was 90%. Today, less than 60 percent of people can answer the equation correctly. The decline in basic academic skills is a blow to major companies that employ engineers.

In 2000, Japan was top in the PISA worldwide ranking for Mathematics, then fell to no. 6 in 2003, and further dropped to no. 10 in 2006. After suffering an achievement crisis, Japan climbed to the 5th ranking in 2015, 2 places up from 7th best in 2012.

Do you know the answer?

A Mathematics teacher gives the correct answer in the clip below.
