We
will learn about the addition of 5-digit numbers (without carrying and with
carrying).
We know how to add 2 or 3, 4-digit
numbers without carrying or with carrying. Now we will apply the same method
while adding two 5-digit numbers (without carrying and with carrying) and three
5-digit numbers (without carrying and with carrying). Arrange the numbers in
columns and then add ones, then tens, then hundreds, the thousands, finally ten
thousands.
Consider some of the examples.
Example No1: Add 12347 and 46152 without
carrying
