For celebrities who lack basic common sense,
Jung Seungje, a famous math teacher, is here 
It starts with a very basic level of elementary school students
Kim Kwang Kyu and Kim Tae Gyun say the answer at the same time
Why is it 24? LOL
Jung Seung-je’s expression that looks really serious
But Kim Tae Gyun didn’t solve it in a normal way either
What kind of miracle logic is this?
During the lecture, Kim Kwang-kyu’s new concept calculation method came out this time
KIM KANG KYU’s new way of calculating
It’s the apple calculation method
He said he used to do it like this is how he used to do it lol
Ah really, Hyunmoo’s joke lol
