... Multiplying: If there are an even number of negative signs, the product is positive. Ex. -3 x -5 x 3 x -2 x -1 = +90 (Happy) If there are an odd number of negative signs, the product is negative. Ex. -5 x 7 x 2 = -70 (Sad) Dividing: If there are an even number of negative signs, the product is posit ...

Lights Out!: A Survey of Parity Domination in Grid Graphs
... Some open problems and future directions are now stated. The first problem is key to understanding the complete solvability of grid graphs. Problem 1 Let p(x) be factor of one of {f2k +1 (x), f2k −1 (x)}, say it is a factor of f2k +1 (x). Can one characterize when is p(x+1) a factor of f2k +1 (x) an ...

... Solution: This question is best done using the Cauchy-Schwarz Inequality – note that it also follows from the Power Mean inequality with r = 1 and s = 2, but that inequality would only apply for a1 , a2 , . . . , an positive, and as such some argument would need to be made for the case where some of ...
