A ditch-digger can dig a ditch in 2 days and another ditch-digger can dig the same ditch in 3 days. What is their average rate of ditch-digging per day?

**The string**:

S_{7}P_{3}A_{31} (Force - Pull).
**The math**:

Pj Problem of Interest is of type *force*. Problems of work are force problems.

Average rate of ditch-digging per day of first digger = 1/2

Average rate of ditch-digging per day of second digger = 1/3

Average rate of ditch-digging per day of both diggers = (1/2 + 1/3)/2 = 5/12.

The *point* **.** is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.
