The Singing Hedgehog Guide to:
Decimal Addition 2

We can also fill in extra zeroes so that each number
is the same size either side of the decimal point.

We still have to remember to:

LINE UP THE DECIMAL POINTS!

Here is an example of this method:

45.6 + 1.72

This becomes 45.60 +
01.72:

       45.6
0

    + 01.72
      
  47.32
              1    
 
            notice that we still do carries as normal.
