Warning: From this page, things will get much harder. The lunchboxes will become more complicated.
But: You don’t need to understand everything immediately. Even if you don’t completely get it, please keep reading!
As promised: If you can solve this problem, I’ll return your mathboxes.
Minion, explain the problem!
Sure. First, take a look at this lunchbox.
We learned on the last page that I can convert this lunchbox to .
Now, take a look at this lunchbox.
Each icon represents a food item.
We now combine the above two lunchboxes.
If you combine them, it’ll look like this:
Now, here’s the challenge:
This is the “very difficult question” I’ve been talking about.
If you solve this, I’ll return your mathboxes!
Hmm… I don’t know if I understood the problem.
And I have no idea how to solve it!
No problem! First, try filling each icon with a random food item.
By doing so, you’ll be able to understand the problem better.
Ok, let me try…
Here it is: I randomly filled each icon with sushi , a sandwich , or a hamburger .
Now, we’ll run the above lunchbox, and…
Ok, let’s run it!
Need a review? To solve the above lunchbox, we’ll need to use the rules from Beginner 5.
If you want to review them, press “Do a Quick Review” below.
Let’s run it!
First: Because there are multiple pairs of 1’s, we start from the leftmost pair.
Press Run . (Or press to step through manually.)
Second: We can’t start with the leftmost pair of 1’s because there’s only one item on the bottom (a sandwich ).
Therefore, we do the pair of 2’s.
Press Run :
Third: We’ll need to start with the pair of 2’s again, just like the last time.
Press Run :
So this is the final result!
Now, we want to convert this to a mathbox…
But unfortunately: I won’t be able to convert this.
Why not? Because it doesn’t follow this pattern:
There needs to be exactly one on the top-right, but that’s not the case here.
Hmm… if the top-right was a hamburger instead of a sandwich , it could have been converted to .
It was so close!
So: Because it didn’t become a lunchbox that can be converted to at the end…
Your answer was incorrect.
Hopefully you understood what the problem is asking. So let’s state it again:
Again: The “random” lunchbox you came up with was incorrect.
Try to see if you can come up with a different one that works!
Hmm… I now understand the problem, but I don’t know how to solve it!
The villagers are so close to getting their mathboxes back, but they’re struggling. Let’s see if they can solve it on the next page!
