Here are the original 27 equations (loosely defined) that led to what are now called “ditloids”. Enjoy them. They are not a test of intelligence. Just play with trying to solve them. Make it a group effort and give hints until everyone has solved all the items.
1. M. + M. + N.H. + V + C. + R.I. = N.E.
2. “1B. in the H. = 2 in the B.”
3. 8D. - 24H. = 1 W.
4. H.H. & M.H. at 12 = N. or M.
5. 3 P. = 6
6. 4 J. + 4 Q. + 4 K. = all the F.C.
7. S. & M. & T. & W. & T. & F. & S. are D. of the W.
8. A. + N. + A.F. + M.C. + C.G. = A.F.
9. T. = L.S. State
10. 23 Y. - 3 Y. = 2D.
