Ding! Ding! Take your desks, everyone. For today’s lesson, we’ll be attempting to solve Landau’s problems, a series of mathematical equations proposed by Edmund Landau in 1912 that are so difficult, they remain unsolved by modern mathematicians. If you can’t solve them, you get an F.
Just kidding, but we do have a totally tough puzzle for you:
Using the clues provided, can you determine what the ruler equals?
Last week we challenged you to find a pattern in the incomplete words. If you filled them in correctly, the answer should look like this:
The pattern, then, is that the missing syllables sound like the consecutive even digits two (TUna), four (comFORt), six (forenSICs), eight (skATEboard) and ten (TENderly).
