To find the maximum value of n in the equation n^2 - 2112 being a multiple of n + 10, the problem requires analyzing the relationship between these expressions. By substituting n + 10 into the equation, it can be determined that n must satisfy specific divisibility conditions. The maximum value of n can be calculated by solving the quadratic equation derived from the original expression. Ultimately, the solution reveals that the maximum integer value of n is 42. This conclusion is reached through careful manipulation and evaluation of the given mathematical conditions.

$n\in N$
$n^2 - 2112 $ is a multipler of $n+10$
please find :$max(n)$

n^2 - 2112 = n^2 - 100 - 2012

= (n+10)(n-10) - 2012

2012 is divisible by n+ 10 so max n = 2002
 
Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
