> On a certain day, 278 people entered the park.
I didn’t test this with robots, but I tested this with humans (first year university students). It’s more difficult than expected, because it has to be translated as 1 * X + 1 * Y = 278, but neither of the “1” coefficients are written in the text. It breaks the “easy” algorithm that is “copy all the numbers in the matrix, and hope that the solution is related to the problem”.

Peter Norvig covered STUDENT (http://en.wikipedia.org/wiki/STUDENT_(computer_program)), a program that solves algebra word problems, in "Paradigms of Artificial Intelligence Programming: Case Studies in Common Lisp" back in 1992.
Perhaps also of interest in this context is the work of Gordon Novak (http://www.cs.utexas.edu/users/novak/) in the 1970s, related to AI/NLP interpretation of elementary physics problems [1].

Yes but it doesn't understand. Let's say I gave it something more complex like, "let's call plus one meow. What is meow of two?" I bet most third graders would get this correct.
No link to the paper?
