Aligning both the numbers according to Place Value table,
For adding these two numbers we need to add the like terms of both the digits together i.e. digits at ones place will be added together, digits at tens place will be added together and so on..
So, adding Ones place digits, we get
Now, adding digits at Tens place,
As we know that,
13 Tens
=10 Tens
+3 Tens
10 Tens
+3 Tens
=1 Hundreds
+3 Tens
So, we will keep
3 at the Tens place and give
1 as a carry to Hundreds place.
Similar operations will be done for addition of rest of the digit's places, as depicted in figure below,
Therefore,
378,922,464+488,059,273=866,981,737
