[ad_1]

The operation to search out the full of various values is

known as addition.

● Once we sum up two or extra quantities we use addition.

● The signal of addition is +

● Add numbers in any order, we get the identical sum. e.g.

5 + 6 + 7 = 18

6 + 7 + 5 = 18

7 + 5 + 6 = 18

● Zero added to any quantity offers the identical quantity. e.g.

8 + 0 = 8

0 + 10 = 10

32 + 0 = 32

0 + 88 = 88

● Add 1 to a quantity, we get the following quantity. e.g.

11 + 1 = 12

40 + 1 = 41

1 + 76 = 77

1 + 99 = 100

**Add:**

5 + 0 =

0 + 25 =

15 + 1 =

68 + 1 =

22 + 8 + 5 =

5 + 8 + 22 =

8 + 5 + 22 =

5 + 4 + 3 + 2 =

6 + 7 + 5 + 0 =

9 + 1 + 4 + 7 =

**Broaden and add:**

(i)

30 + 7 30 + 20 50 |
+ + + 59 |
20 + 2 7 + 2 9 |

(ii)

** 245 + 652**

200 + 40 + 5 + 600 + 50 + 2

200 + 600 + 40 + 50 + 5 + 2

800 + 90 + 7

Tell us some information about addition which is able to assist us to be taught so as to add 4-digit and 5-digit numbers.

**1.** Addition of small numbers might be accomplished horizontally.

Instance: 6 + 2 + 3 = 11

**2.** Massive numbers are added in vertical columns (written underneath the place worth chart).

Instance:

Th H T O

7 2 5 8

1 3 6 2

__ + 1 4 2 6__

__ 1 0 0 4 6__

**3.** A zero added to a quantity doesn’t change the place worth

of the quantity.

H T O

3 2 5

__ + 0__

__ 3 2 5__

**4.** The quantity or values being added are known as addends and

the reply known as the sum.

**5.** 1 added to a quantity offers the successor of the quantity as

the sum.

**6.** To discover a lacking addend in an addition sum, the given

addend or the sum of all of the given addends is subtracted from the given sum.

Workings:

**7.** Altering the order of the addend in an addition sum does

not change the reply.

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

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

**8.** Whereas including greater than two numbers, we will group any two numbers

first. It doesn’t change the sum.

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

or

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

19

This truth helps us to group any two addends to make addition

straightforward.

Instance:

= (95 + 5) + 23

= 100 + 23

= 123

Let

us have a fast evaluation of what we’ve learnt about addition of 3- digit quantity

within the earlier class.

So as to add 2- digit numbers, the numbers are

written one beneath the others. The tens and ones digits ought to seem are beneath

the opposite.
