An nxn multiplication table contains n squared entries. How many of
these entries are even numbers? Assume the table begins at 1x1. For
example, 1x1 has no even numbers, therefore 0 entries, 2x2 has 3 even
numbers, 3x3 has 5 even numbers, 4x4 has 12 even numbers, 5x5 has 16
even numbers, 6x6 has 27 even numbers...... What would be the equation
for nxn if n were any whole number, how many even numbers to that n
