Addition of 3-digit numBers without regrouping

Rinki donates `729 and Pinki donates `210 monthly to the

needy people.

Pinki: Rinki, can you say how much do we donate together?
Rinki: To know our total donation, we have to add 729 + 210.

Pinki: Okay, let us add these numbers using a place value table.

First write the numbers in columns and then add.

Step 1. Add the ones. Step 2. Add the tens. Step 3. Add the hundreds.

9 + 0 = 9 ones 2 + 1 = 3 tens 7 + 2 = 9 hundreds
H t O H t O H t O

7 2 9 7 2 9 7 2 9
+ 2 1 0 + 2 1 0 + 2 1 0
9 3 9 9 3 9

Thus, 729 + 210 = 939.
That is, their total donation is `939.
