Hello, this is knowledge sharer Jeong Hyeon-woo. I'm sorry 😢.. Currently, I have to completely renew the lecture due to the library closure, but my personal schedule overlaps perfectly with the renewal period ㅜㅜ So I'm uploading the lectures sequentially now, so I would appreciate it if you could take note of this. For now, I'm trying to keep the renewal period as tight as possible, so I would appreciate it if you could wait a little bit. I'm sorry 🙇‍♂️ And the part you asked about is confirmed to be the second time in the calculator app section. Please understand this.
