N - N = O

ReplyDeleteOh. I almost commented saying, "Is this a trick? N-N is zero." Then I realized you were looking for which LETTER would represent N-N. I gotcha. (And Anonymous is right: it's O.)

ReplyDeleteWouldn't N-N=Z?

ReplyDeleteO isn't zero in this problem, it's one. The letters are the first letter of the numbers. The problem would read "one plus two = three, one plus six = seven, two plus three = five, four plus four = eight, eight plus one = nine." So, N-N, or nine minus nine, equals zero, which is Z.

The answer should be N-N = Z

ReplyDeleteThe key is

One plus Two = Three

One plus Six = Seven

Two plus Two = Four (or Two plus Three = Five)

Four plus Four = Eight

Eight plus One = Nine

And so Nine - Nine = Zero.

The answer should be N-N = Z

ReplyDeletetht a tricky qsn

The key

One plus Two = Three

One plus Six = Seven

Two plus Two = Four (or Two plus Three = Five)

Four plus Four = Eight

Eight plus One = Nine

And so Nine - Nine = Zero.

Ohhhh...now I get it.
