**Indroduction**

"Ananthan come fast"
Ananthan’s mother shouted.
"Bus would come earlier".

"I am here mummy, I am ready" he said.
The whole family was very busy for
ananthan’s sister marriage. They
have to buy new clothes for their relatives and family members.

They finished their purchase and
returned back home.

Ananthan asked his father ‘how much did
you spend for our dresses?

His father said, “Cost of dresses for
gents is ₹ 25050, for ladies is ₹ 47025 and for kids is ₹ 7125, and for bride
and groom dresses is ₹17500, Now you can tell the total amount.

Ananthan took a paper and pen, he wrote
all the amounts one by one according to their place values.

Check whether, the above total amount is
correct or not.

Yes, ananthan is correct, see the cost
of kids, ₹ 7125, There is a empty place in ten thousand’s place. So Ananthan wrote
down the numbers according to the place value. We learnt about place values of
the numbers. Now we are going to use the method of adding different values of
numbers. Add the following numbers and write down one by one.

137462 + 4005 + 38 + 56734.

**Step 1:** Start by adding the
ones. We have 19 ones in ones places.

**Step 2:** We must regrouping 19
ones to 1 ten and 9 ones.

**Step 3:** Now we can put 1 ten
with ten and write 9 in the ones place.

Simillarly we have to do
the hundred, thousand … and so on.

Arrange all the given numbers according to their
place value. We
can do all the addition problems in this manner.

**Note:**

When
write the numbers, we can avoid mistakes by starting from the right side, that
is from the units place.
