```   the numbers are:  4 1/2, 5, 6 1/2, 7, 8, 8 1/2, 11, 12,
12 1/2, 14, 14 1/2, 14 3/4, 25, 29

River Lodge Too?

the math is:
A = (14 3/4 - 14 1/2) * (11 - 7) + (8 - 5) + (14 - 12) + (29 - 25) = 10
B = (8 1/2 + 12 1/2 - 6 1/2 - 4 1/2) = 10
A = B

...or using decimal numbers...

A = (14.75 - 14.5) * (11 - 7) + (8 - 5) + (14 - 12) + (29 - 25) = 10
B = (8.5 + 12.5 - 6.5 - 4.5) = 10
A = B

...or (to copy and paste into Google's calculator)...

(14.75-14.5)*(11-7)+(8-5)+(14-12)+(29-25)+4.5+6.5-8.5 = 12.5

rsAgeEval: A = ((11 - 8) * (29 - 25)) / (1/4)) = 48
B = sqrt(12.5 - 8.5) + (6.5 - 4.5) - (7 - 5) - (14 - 12) = 0
A + B = 48
* RoadHacker was 48 years young when he found this sign.

rs42Eval:  A = ((11 - 8) * (29 - 25)) / (1/4)) = 48
B = (12.5 - 8.5) + (6.5 - 4.5) + (7 - 5) - (14 - 12) = 6
A - B = 42
