Question

7*11*13=

Answer 1

I suggest you to take the larger numbers first and then you can multiply them. (11*13)

Then use that product to multiply it by 7 (x*7).

That will get you your answer :)

Answer 2

I can't believe you can't solve this yet you solved a logarithm problem.

Answer 3

11*13=10*13+13=130+13=143

Answer 4

7*143=7*100+7*40+7*3=700+280+21=

Answer 5

is this really the best method?

Answer 6

That is called the partial-products, I believe. It is kind of hard as a strategy. But I just simply Guggenheim you to multiply 11*13. Then that product (we will say x) will be multiplied by 7.

Answer 7

I don't know what "Guggenheim" means. My iPad just auto-corrected this. :(

Answer 15

Answer 16

@UnkleRhaukus You are correct! And that is a "nice" result. :)

Answer 17

What I do is realize that 7 is really (10-3) and 13 is (10+3) which makes it easy to multiply together since that's just: (100-9). Then multiply that by 11 which is of course (10+1) and get 1000-90+100-9 and bam you can see the middle terms comes to be 10, and the last term is -9 so you really just have 1001.
