Addition is the method by which we can add two or more quantities. Therefore, in an addition two or more numbers are involved. Before knowing the rules of the addition, look at the following.

Therefore,

$9+5=14$

The following are the rules for the addition of more than one digit numbers.

Rule: 1

Start addition with the 1st digit from right, then with 2nd digit from the right and the process goes on.

In another words, add ones 1st: then tens: then hundreds and so on.

$14+15=?$

Rule: 2

If addition of one’s gives result in 2 digits, then add the left digit of the result with tens and the process goes on.

$25+26=?$

Here, the left 1 of 11 is added to 4 as below:

• Example:

The following are the stock of the given articles in a general store:

 Name of articles Quantity (Pieces) Soap 33 Tooth brush 11 Chocolates 13

How many articles are there in all?

(a) 23                                        (b) 44

(c) 57                                        (d) All the above

Explanation: Therefore, option (b) is correct.

Let’s understand it through the following examples:

• Example:

{17} + {12} + {13} =?

Trick:

Addition of images means grouping of more than one images into a single group.

In the

${{2}^{nd}}$

example we add group of [6] faces with group of [3] faces and get the result as the group of [9] faces.
