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:
45.60
+ 01.72
47.32
1
notice that we still do carries
as normal.
