The operation to find the sum of different values ​​is called addition. Let us know some adding facts that will help us learn how to add 4 digit and 5 digit numbers.

1. Adding small numbers can be done horizontally.

Example: 6 + 2 + 3 = 11

2. Large numbers are added in vertical columns (written under the location value table).

Example:

Th HT O.

7 2 5 8

1 3 6 2

+ 1 4 2 6

1 0 0 4 6


3. A zero added to a number does not change the place of the number.

HT O.

3 2 5

+ 0

3 2 5

4th The number or values ​​that are added are called the addends, and the answer is called the sum.

5. 1 added to a number gives the successor of the number as a sum.

Additional facts

6th To find a missing addend in an addition sum, the specified addend or the sum of all specified addends is subtracted from the specified sum.

7th Changing the order of the addend in an addition sum does not change the answer.

Example: (i) 45 + 26 = 26 + 45 = 71

(ii) 3 + 2 + 6 = 6 + 2 + 3 = 11

8th. While adding more than two numbers, we can group any two numbers together first. It doesn’t change the total.

Example: 7 + (9 + 3) = 7 + 12 = 19

or

(7 + 3) + 9 = 10 + 9 = 19

This fact helps us group any two addends for ease of adding.

Example:

= (95 + 5) + 23

= 100 + 23

= 123

Let’s give a quick look at what we learned about adding a three-digit number in the previous class.

To add two-digit numbers, the numbers are written one below the other. The tens and units should be below each other.
