Math for Kids/Logic Puzzle
QUESTION: Hello my friend. I suffer terribly from Ritalin induced eye pain but here is my question:
Can you help me, step by step, on how to solve this logic problem. Please see attached image.
ANSWER: Hello, Peter.
Admittedly, I was stumped. I had to ask another person. E/R = D/S = N/U = L/W.
Why L? The answer lies in realizing that the letters represent directions. N, S, W, and E stand for North, South, West, and East. North is "up"; South is "down"; West is "left"; and East is "right." (At least on a map or typical compass this is the case.)
I'm not a fan of this sort of thing because, without numbers, there's no reason to necessarily believe that L/W = E/R. It's an arbitrary assignment based on directions. It'd be better if the problem listed a string of letters, with the last one unknown. Making this into a "math" problem only confuses the issue.
There aren't really any steps in solving this. You just need to think it out.

QUESTION: I suddenly noticed another pattern. If you look at
E/R = D/S = N/U = L/W,
you in ill notice that it is the order of the alphabet, going from left to right, starting from R then S in the denominator.
It then skips out T and V.
In the divisor, the alphabet goes from right to left, D, E and then L, N, skipping out M.
That is true, but it's just another ad hoc "solution" to this "math" problem. Actually, it's probably worse than the direction answer: E goes back one to give you the next numerator, D, but N goes backward (skipping one letter) to give you L. For the denominators, R goes forward one to give you S, but U then skips a letter to give you W.
There's no pattern to this solution. N skipping backwards to L doesn't seem to fit.
