"I can make love," is not a sentence a 7th grade teacher wants to hear coming from a 7th grade student, especially when the student in question is saying this directly to him.
I mean, The Police have a song about this. And the police enforce laws about this. Also: ew.
However, this innocent lamb went on to show that if you enter 3^07 on a calculator and turn it upside-down, you have, indeed, "Made 'Love'," as it were. I'm pretty sure she had no clue what she said. A nicer teacher would have said, "That's great, but please don't go around telling people you can make love."
Oh, to be a nicer teacher...
