If you had not had the answer under a spoiler, I would have used option one.
What is 7 times 47? - chrome - 2009-08-05
7 * 4 * 10 + 35 + 14
or if you want it totally unsolved...
(7*4) * 10 + (7*5) + (7*2)
I've always used round numbers (stuff ending in 0 or 5) to calculate odd ones (actually, the equation I put up there would be more like ...35 + 10 + 4, how I've always done it). I still memorize my twos, threes, fours, etc. from second grade, so I have no problem doing stuff like this...

First option, except for the multiplying by ten part. I just automatically calculate 7*40 instead of 7*4*10.

I voted "other". I did (7 *40) + (7 * 7) in my head.

interestingly, as many chose method 1

... 7*47... I did it straight.
However, if I had to guess, I did 7*50 - 21, and just didn't think about it. 'Spose it comes naturally.

Mentally adding unaligned numbers is fun.

I asked Chuck Norris... He scared the problem solved.

I did the math in my head. Didn't picture any paper or pencil, just floating numbers. I also vocalize in my head what I'm thinking to help me keep track of what I'm doing.

7 time 40 = 280
plus 7^2 = 329
I did it the same as heidi
What is 7 times 47? - Nikkey - 2009-08-05
7^3 - 7 * 2
Strictly speaking the same a 7 * 50 - 7 * 3.
What is 7 times 47? - Spaz - 2009-08-05
((47 * 2) * 3) + 47
