Step 2- Check the digits in ones



                  place.








                                                   T                 O



                                                   2                 18


                                                   3                  8


                                    -              1                  9










                   We can not subtract 9 from 8  as 9>8. So



                   we take one of the tens from tens place


                   to ones place.


                   ( Remember 1 ten =10 ones)
   1   2   3   4   5   6   7   8
