> You say “OK, so f(10)=x ✱ x”
“f(10) is x times x”
Holo says, nodding.
“I think I get it.”
Holo says, smiling again.
“Let’s try some more!”

> You say “Now try: f(f(1)) = 16, solve for i”
“f(f(1)) is 16…”
Holo says, deep in thought.

> You say “You can actually brute force this. Try all the numbers starting at 1 until you get the correct result”
“I don’t get it, what do you mean?”
Holo says with a confused look on her face.

> You say “Ok, so just start at 1 and put 1 into f(f(1)). If that’s not the answer, try the next number”
“Ohh!”
Holo says with a huge smile, understanding.
“I get it, I get it!”
“Let’s see… f(f(1)) is 16…”
Holo begins trying different numbers.
“f(f(1)) is 16…”
Holo says, putting 1 into f(f(1)).
“Nope!”
Holo says, then tries 2.
“f(f(2)) is 16…”
Holo says, smiling as the number 2 pops up on the screen.
“Yes! I did it!”
Holo yells excitedly.
“I can’t believe I got the right answer on my first try! I’m awesome!”
Holo beams.

> You say “So what’s the answer?”
“f(f(1)) is 16… and the answer is i=2.”
Holo says, typing it into the terminal.
“Please tell me I got it right this time!”
