Correct! It's one that keeps people guessing as they often assume it's going to be something ending in ING.

Yep, I wasted a lot of time trying to come up with something ending in ING

No-one?

Does it have to conform to the "proper" rules of equations? In other words, if I moved the 1 to the left-hand side of the equation, would it now become a negative? If not, you could have:

1 + 101 - 102 = 0 (I know, I'm pushing it a bit here...)

I can see I've been imprecise. Move one digit to make the equality correct.

(But no, you're not allowed to add a plus sign.)

Well done Billi. That was driving me mad.

While I solved this a complicated mathematical way, there's also a simpler mathematical way to solve it:

In the first scenario there are 77 goat days of food. In the second case, there is 80 goat days. Therefore the field produces enough grass each day to sustain 3 goats, and so the 3 goats could live there forever.

Another little math task: SECHS +SECHS -------- ZWOELF Replace the letters with the right numbers! Sorry, couldn't manage to get the letters straight one beneath the other, but I'm sure you know what is meant!

E must be >=5, sinze W≠F F must be even W must be F+1 F can't be zero, since Z=1 and W≠Z S must be > 5 since Z=1 and F≠0 L must be odd since S>5 None of the top letters can represent zero, as the corresponding sum would be the same letter or Z (1), which doesn't happen. With these restraints, it's fairly easy to go through the possibilities. Last edited by pdurrant; 01-07-2013 at 08:30 AM.
