Multiplying 3+9Date: Tue, 15 Nov 94 9:45:39 EST From: Binford M.S. Gifted Program Subject: math question (3+9(3(3+9(3+9(3+9(3+9(3+9))))))) Thanks. Date: Tue, 15 Nov 1994 11:11:32 -0500 (EST) From: Dr. Ethan Subject: Daniel's question Daniel, What a neat use of multiplication and addition. Before I answer I wanted to point out to you that the pattern is broken at one point. Did you mean for that to be the case? Just in case you didn't I will answer both ways. First your way. (3+9(3(3+9(3+9(3+9(3+9(3+9))))))) = 2192187 Or you might have meant (3+9(3+9(3+9(3+9(3+9(3+9(3+9)))))))= 6576582 Why don't you try to do this on a calculator and write down what you get after each step and see if you can get a pattern.
