879.6748 + 615.097
 
Place one number above the other so that the bottom decimal point is directly below and lined up with the top decimal point. Draw a line under the bottom number. If necessary add zeroes to the right of the decimal point to make it easier to align the columns.
 
          
  879.6748
+ 615.0970
          
 
Add the digits 8 and 0 (8 + 0 = 8) and place the answer below the line in the column being added.
 
          
  879.6748
+ 615.0970
         8
 
Add the digits 4 and 7 (4 + 7 = 11). The sum is more than 10, regroup digits placing the 1 above the column on the left, and place the 1 below the line in the column being added.
 
       1  
  879.6748
+ 615.0970
        18
 
Add the digits 1, 7 and 9 (1 + 7 + 9 = 17). The sum is more than 10, regroup digits placing the 1 above the column on the left, and place the 7 below the line in the column being added.

      7718
 
Place the decimal point in the answer directly below the decimal points in the terms.
 
          
  879.6748
+ 615.0970
     .7718
 
Add the digits 9 and 5 (9 + 5 = 14). The sum is more than 10, regroup digits placing the 1 above the column on the left, and place the 4 below the line in the column being added.
 
   1      
  879.6748
+ 615.0970
    4.7718
 
Add the digits 1, 7 and 1 (1 + 7 + 1 = 9) and place the answer below the line in the column being added.
 
   1      
  879.6748
+ 615.0970
   94.7718
 
Add the digits 8 and 6 (8 + 6 = 14). This number is more than 10 but there are no more columns to be added, place the answer below the line in the column being added.
 
          
  879.6748
+ 615.0970
 1494.7718
 
Final answer
