I know this, but I believe you have to do something to all the numbers, do you have to put them from least to greatest?

stack them and move them about to make life simpler

A: {            2, 4, 6,      8, 10,       12}
B: {−2, −1, 2, 4,     7,            11     }

now drop down all the columns
