How can you use partial products with 23 times 17?

You could use 23 * 17 = 23*(20 - 3) = 23*20 + 23*(- 3) = (20 + 3)*20 + (20+3)*(-3) = 20*20 + 3*20 + 20*(-3) + 3*(-3) = 400 + 60 - 60 - 9 = 391. I would however not that the two numbers are 20+1 and 20-3 and so look at the questions as a difference of two squares (DOTS). The answer, then is 23*17 = 202 - 32 = 400 - 9 = 391 So much shorter and simpler.
