### Eleven, 11, XI

Multiply x * . () by eleven:
11 groups of or 11 lots of
For 0 to 9x11 just write the number twice 3x11=33 and 7x11=77
Times by 10 then add another

Divide ÷ / by eleven:
How many times does 11 go into
Break into 11 groups
Reverse 11x tables 3x11=33 so 33÷11=3 and 33÷3=11

Add 1 to the tens and 1 to the ones digit

Take - eleven:
Take 1 from the tens digit then 1 from the ones digit
Take 1 then take 10
