No! Sensei! I don't understand a thing!

Erm... Bakushin O-san?

If you don't understand, then could you perhaps make a face that shows that, even a little...?

Yes! Understood! I shall try!

R-Right...

For this question, use the formula that I just taught you like this...

The next problem can be solved by applying the calculations from the previous problem in reverse.

Well now... that's a face that's full of confidence...

Bakushin O-san, have you solved all the problems?

Now that's a face that screams "I don't understand a word you said"...

No matter what, give it your all! That's a class rep!
