You can do it for any large number multiply by 11, basically what you do is bring down the first any last number than add the two number together and but it in between the first number and the last number...so 11 x 12, bring down the 1 and the 2 then 1+2 =3 put 3 in between the 1 and 2. 14 x 11, bring down the 1 and 4, then 1 + 4 = 5 and put 5 in between 1 and 4. Check yourself it works for any large number multiply by 11, there is another method that works for multiplication of 10...]]> jj Math Fri, 02 Jan 2009 05:15:24 -0700
