[pokawiwi]

dude i know how 11 time 3 lets say 33 it will repie!

[Onsomemoonshine]

Lol why dont you just times it by ten and add the number on again

E.g:

3442234 x 11 =

3442234 x 10 + 3442234 = Some number I cant be bothered adding.

Ok yep now I see why its good to know this.

A variation on this trick for 3 digits:

(a) to (d) are the digits 1 to 4

Step 1: Just as in the trick in the video, the first and last digits remain the same.

Step 2: (b) is digit 1 + digit 2 of the original number.

Step 3: (c) is digit 2 + digit 3 of the original

11 x 153

Step 1. (a) (b) (c) (d) -> 1 (b) (c) 3

Step 2. (b) -> 1 + 5 = 6 -> 1 6 (c) 3

Step 3. (c) -> 5 + 3 = 8 -> 1 6 8 3

it is not silly for people who have alearning disabilty this helps so stop bagging

[erasmusso]

stupid trick! I think it's better to do:

11 x 99

(10 + 1) x 99

10 x 99 + 1 x 99

990 + 99

=1089

would be better is u just add from right to left.... 11x99.. the ones place is 9 and 9+9 is 18 so write down the # in the ones place which is 8 so now u have 89 and then just add the 1 to the 9 which is 10 so now u have 1089... or 11x24357= 267927
