Consider, for example, the number 420109. It's quite big, isn't it? Not so far from half a million. Yet it can be interpreted to be smaller than a hundred with a very simple trick, without putting any mathematical operators between the digits, without using any mathematical function on it, and without erasing or hiding parts of it.
There are a few other 6-digit numbers this could work with, but not many.
Not only can it "be made smaller", 420109 actually is smaller than 100 from a certain viewpoint. There are very few 6-digit numbers where this can be applied.
Although I really like Bass' idea, I want to offer another, rule-bending, idea:
Put in a decimal point (or a comma, depending where you live) and make it 4.20109
Now the number is definitely below 100 without breaking the rules:
- Putting in a single pixel is as easy as it gets (and we don't need to learn another language!)
- Not a mathematical function
- No hiding or erasing of numbers
- Not a mathematical operator (although a mathematical symbol)
The first thing I saw was how the shapes of the letters match up. By transposing the 2 on the top of the 4, it becomes a funky looking 4, but still a 4. Then place the 1 on it as well. Still a 4. Then the 0's can be slightly shrunk and placed on top part of the nine.
I hope I'm at least on the right track. Otherwise, I'm crazier than I thought.
Sorry, in a rush. I was the best picture I could do:)
This is the stupidest solution I've ever cooked up, but here it is anyway.
Turn the 1 sideways to make it a divisor for a fraction. Now you get 420/09, which comes out to be way less than 100. This is, of course, monumentally stupid and I hate it. If it's the right answer, I will be sad.
