Subtraction with borrowing - Step 1






       Now we have to start subtraction.
                                         13

                       H      T       O
                       7       5       3

                  -    3      7        8


       Starting from ones-place column, as 3 is smaller than 8, so

       1 ten = 10 ones is borrowed from tens-place column. Now, ones-place
       column value is 10 ones + 3 ones = 13 ones. 13 > 8. So, we can easily

       subtract 13 ones – 8 ones = 5 ones. We have to write 5 under ones-place
       column.
   As we have borrowed 1 ten from Tens-place column so now in Tens-


   place Minuend has become 5 tens – 1 ten = 4 tens.

                                                            4        13

                                                  H       T        O

                                                  7        5        3

                                            -      3        7        8


                                                                        5
