I read your post dear that's too nice. You tried to mention my name but unfortunately spelling mistake; it's okay.
You said you were out of Steemit for two months. We welcome you here to steemit again and it's our pleasure to do interaction with such an expert as you.
I have students with me too I m teaching them math.
My own subject is English and I have command on it, but since my childhood I m good at math and I can do whatever tough question it is.

Lots of love and respect to you teacher
