### Logic Number Puzzles

If each of the following equations is true, what is each letter? The rules are: (1) all the variables are equal to integer values between one and the number of variables in the puzzle, and (2) none of the variables are equal to each other. For example, if there are six variables, each will equal a number from 1 to 6. Since no variable equals another, all six values will be used.
1. A + B = D
2. B + F = E
3. C + D = E
4. B does not equal 1.

1. A=3
B=2
C=1
D=5
E=6
F=4

Simple algebra and some logic.

2. Aw, I was just about to say that!

3. just as don says.

4. And, of course, I agree with you all:
A = 3, B = 2, C = 1, D = 5, E = 6, F = 4
