Maybe you’re not all that interested in studying math in Korean but if you’re fully immersing yourself in the language and may be considering moving to Korea and potentially teaching there, this video may be useful for you.
I found this while I was searching for videos to listen to while I work and I ran across this series from the channel KoreanBabo with Jemma. I don’t know if she still posts videos because the lasts few I saw were from a year ago. But she has a lot of useful information on her channel! So for all my YouTube followers, this will probably be a good channel to check out.
The video is 100% in Korean with English subtitles and it’s really short and easy to follow.
