He Stood and Delivered

Jaime Escalante taught advanced math to low-income minority students at a time when nobody believed it could be done. He was such an extraordinary teacher that he inspired the hit 1988 movie Stand and Deliver (available on DVD). Escalante's death last week was a major loss for the math community, but his impact lives on.

Here is a fun trick from Escalante, just one of the ways he brought math to life. Write the numbers 1 to 10 down the side of a piece of paper. Multiply each number by 9 and write down the products so they form a column (all the ones digits and tens digits lined up). What pattern do you notice in the ones and tens digits?
