Multiplication by 11 is simple. For a 2-digit number just add the two digits of the number multiplied by 11 and place the sum in between that number carrying any ones overs.

19 x 11

1 + 9 = 10  (you will carry the 1 )
take the first number (19) and spread out the 1 and 9
1 ____  9
put the sum in the middle using only the last digit. Carry the ones, if any over.
1     9
1 0
-----------
2 0 9

Easy. No calculator needed!

wrong. the correct answer is 361. looks like there WAS a calculator needed. check the calculator next time, or at the least, learn how to add and multiply.

"whizkid"...okay... >_<

I did use a calculator (windows 10) and I got the same answer as whizkid. I think you're wrong Reagan.

p.s flagging is reporting something innapropiate not incorrect.
