Let’s try another:
48 X 11
again, leave the 11 alone for a moment and work with the 48
4 + 8 = 12
So now we have to put the 12 in between the 4 and 8 but don’t do this:
4128 as that is wrong...
First, do this: Place the 2 from the twelve in between the 4 and 8 giving 428.
Now we need to input the 1 from the twelve into our answer also, and to do this just add
the one from 12 to the 4 of 428 giving 528!
Ok, one more
74 X 11
7+4 = 11
7 (put the 1 from the right of 11 in) and 4
then add the 1 from the left of 11 to the 7
74 X 11 = 814
This is a really simple method and will save you so much time with your 11 times tables.
