Problem 1
How many of the integers between 1 and 1000, inclusive, can be expressed as the difference of the squares of two nonnegative integers?
Problem 2
The nine horizontal and nine vertical lines on an checkeboard form
rectangles, of which
are squares. The number
can be written in the form
where
and
are relatively prime positive integers. Find
