Question: what are math arrays?

 

Jeff,

An array is a rectangular arrangement. For example it might be a 3 by 2 be a rectangular arrangement of numbers (mathematicians always mention the number of rows first then the number of columns)

3 6
5 9
0 7

or it might be a 2 by 4 array of symbols

% + + $
+ * - &
