If:
O plus T = T
O plus S = S
T plus T = F
F plus F = E
E plus O = N
What is N - N?

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.
