While adding numbers of different number
of digits, we have to be careful in putting
the numbers one below the other.
All the digits of the units' place
should come one below the other.
Similarly, all the digits of the tens'
place should come one below the other.
And all the digits of the hundreds' place
should come one below the other.
See the vertical presentation
of the process given below.
See how the numbers 678, 97, 9 are placed one
below the other in the above presentation.
In 678, 6 is in hundreds' place, 7 is in
tens' place and 8 is in units' place.
In 97, 9 is in tens' place and
7 is in units' place.
In 9, 9 is in units' place.
All the digits of the units place
have to come one below the other.
Thus, you find 8, 7 and 9 one below the other
in the units' place in the above presentation.
Similarly, you find 7 and 9 one below the other
in the tens' place in the above presentation.
You find only 6 in the hundreds' place.
First, the digits in the units' place
are added ( 8 + 7 + 9) to get 24.
In this 24, 4 is placed in the units'
place of the answer and 2 is placed
under the digits in the tens' place.
Then, add the digits in the tens' place
including the small 2 carried over from
the units' place,(7 + 9 + 2 ) to get 18.
In this 18, 8 is placed in the tens'
place of the answer and 1 is placed
under the digits in the hundreds' place.
Then, add the digits in the hundreds'
place including the small 1 carried over
from the tens' place,(6 + 1 ) to get 7.
This 7 is placed in the hundreds'
place of the answer.
Thus the answer is 784.

Progressive Learning of Math : Addition Sums
Recently, I have found a series of math curricula (Both Hard Copy and Digital Copy) developed by a Lady Teacher who taught everyone from Pre-K students to doctoral students and who is a Ph.D. in Mathematics Education.
This series is very different and advantageous over many of the traditional books available. These give students tools that other books do not. Other books just give practice. These teach students “tricks” and new ways to think.
These build a student’s new knowledge of concepts from their existing knowledge. These provide many pages of practice that gradually increases in difficulty and provide constant review.
These also provide teachers and parents with lessons on how to work with the child on the concepts.
The series is low to reasonably priced and include
There is an exclusive, Parent Information Page provides YOU with detailed reports of your child’s progress so you can monitor your child’s success and give them encouragement. These Reports include
Time spent using the program
Personalized remediation curriculum designed for your child
Details the areas of weakness where your child needs additional help
Provides the REASONS WHY your child missed a concept
List of modules accessed and amount of time spent in each module
Creates reports that can be printed and used to discuss issues with your child’s teachers
These reports are created and stored in a secure section of the program, available exclusively to you, the parent. The section is accessed by a password that YOU create and use. No unauthorized users can access this information.
