Nah, it's the SAG, v. 0.9, pdf format, and it says (in the copyright) "...no back cover texts". The last line, in the footer on page 122 is "Glossary (DRAFT, but not for long hopefully) 122" does that count?
"The work required for the HCF is duly exhibited in the margin"
It's a school maths textbook from 1924 that I got in a charity shop, and it's wonderful.
It has hundreds and hundreds of problems like this : "If 124 men in 5 1/2 days of 11 hours each dig a trench 232 1/2 yds long, 3ft 8 ins wide and 2ft 4 ins deep, in how many days of 9 hours each will 36 men dig a trench 337 1/2 yds long, 5ft 7 1/2 ins wide, and 3 ft 6 ins deep, supposing that in the same time each of the second set of men does 1/6 more than each of the first set?"
You'd be paying them for just over 29 days work, so we'll make it thirty for agency purposes.
And yes, I did it all by hand, including very long division: it's all over four sheets of paper! Workings as follows:
For the first hole, you have 7502 man hours of work (5.5 days x 11 hours x 124 workers) to dig a hole of 9949632 square inches (First convert all the dimensions into the same scale - inches is the easiest, which makes it 8076 x 44 x 28 - then multiply togather), which is roughly 1326 (Just over, about 1326.25) square inches of hole per man hour worked.
For the second hole, they work 1/6 more efficiently than the first hole, and so they will be digging (1326 x 1/1/6) 1547 square inches per man hour. A day in this trench is nine man hours long, so that is 324 man hours of work per day. The hole's dimensions are (12150 x 67.5 x 42) 14402500 square inches, which requires 9328 man hours to dig. At 324 man hours per day, this will take a little over 29 days.

And remember - no calculators!
