Adding Decimals

          My made up question -
                                                    147.8 + 245.9 = 394.7
                                                    100.0 + 200.0 = 300.0
                                                     40.0 + 40.0 = 80.0

                  7.8 + 5.9 = 14.7

What is did was first I added 100 + 200 = 300 then I did 40 + 40 = 80 after that I went 7.8 + 5.9 = 14.7 then I added all of the answers together then the answer is 394.7
