Closure roperty that Addition:If a and also b space two whole numbers, climate a + b is additionally a totality number. In other words, the amount of any two whole numbers is a whole number or, whole numbers are closed for addition.Verification: In order come verify this property, let us take any two totality numbers and include them. We uncover that the sum is always a whole numbers as displayed below


7 + 3 = 10 (10 is also a whole number)

0 + 8 = 8 (8 is also a whole number)

29 + 37 = 66 (66 is additionally a whole number)

Commutative home of enhancement / Order property of Addition:

If a and b are any kind of two whole numbers, then a + b = b + a.

You are watching: What property of addition is 0 7 7

In various other words, the sum of two totality numbers remains the same also if the stimulate of totality numbers (called addends) is changed.

The numbers deserve to be included in any order. The sum of twonumbers remains same even if the order of numbers is changed.

For example:

I. 4313 + 3142 = 7455

3142 + 4313 = 7455

Changing the stimulate of the addends, 4313 and also 3142 does notchange the sum.

II. 133 + 142 = 275

142 + 133 = 275

Changing the order of the addends, 133 and 142, go notchange the sum.

Verification: In order to verify this property, permit us consider some pairs of entirety numbers and include them in two various orders. We find that the sum remains the exact same as presented below: 9 + 3 = 3 + 913 + 25 = 25 + 130 + 32 = 32 + 0

We can include two numbersin any order.

6 + 3 is exact same as 3 + 6

6 + 3 = 3 + 6

Existence of Additive identification of enhancement / identity Property of addition / Zero residential or commercial property of Addition:If a is any kind of whole number, thena + 0 = a = 0 + a

In various other words, the amount of any kind of whole number and zero is the number itself. That is, zero is the only entirety number the does not readjust the worth (identity) of the number the is included to.The entirety number 0 (zero) is called the additive identification or the identity element for enhancement of whole numbers.

The number continues to be the same when zero is included to the number.

For example:

I. 5918 + 0 = 5918

Identity that 5918 stays the very same when included to zero.

II. 45 + 0 = 45

Identity that 45 stays same when included to zero.

Verification: In order to verify this property, us take any type of whole number and add it come zero. We find that the sum is the whole number itself as shown below:5 + 0 = 5 = 0 + 527 + 0 = 27 = 0 + 27137 + 0 = 137 = 0 + 137Note:Zero is referred to as the additive identity since it maintains or go not adjust the identity (value) that the numbers throughout the operation of addition.

Addition of Zero:

Associativity of enhancement / Associative property of Addition:If a, b, c are any kind of three entirety numbers, then(a + b) + c = a + (b + c)In other words, the addition of whole numbers is associative.

When 3 or much more numbers room added, the sum remains the same regardless that their group or place.

For example:

I. 4610 + 1129 + 2382 = 5739 + 2382 = 8121

   4610 + 1129 + 2382 = 4610 + 3511 = 8121

   4610 + 2382 + 1129 = 6992 + 1129 = 8121

Grouping the the addends does not change the sum.

II. 23 + 45 + 16 = 68 + 16 = 84

     23 + 45 + 16 = 23 + 61 = 84

     23 + 16 + 45 = 39 + 45 = 84

Grouping the the addends go not change the sum.

Verification: In order to verify this property, us take three totality numbers, to speak a, b, c and also find the worths of the expression (a + b) + c and a + (b + c). We find that the values of these expression remain same, as presented below;(i) (2 + 5) + 7 = 2 + (5 + 7)then, 7 + 7 = 2 + 1214 = 14(ii) (5 + 10) + 13 = 5 + (10 + 13)then, 15 + 13 = 5 + 2328 = 28(iii) (9 + 0) + 11 = 9 + (0 + 11)then, 9 + 11 = 9 + 1120 = 20

Let us consider any three whole numbers a, b, c.

We have, (a + b) + c= (b + a) + c = b + (a + c) = b + (c + a) = (b + c) + a = (c + b) + a

Property of Opposites the Addition:

For any real number a, there is a distinct real number –a together thata + (–a) = 0 and (–a) + a = 0The amount of the real number (a) and also its opposite genuine number (-a) is zero climate they are recognized as the additive inverses of each other.

Verification:

5 + (-5) = 0 and (-5) + 5 = 0

or, 5 - 5 = 0 and also -5 + 5 = 0

Here 5 is genuine number and also (-5) is it"s opposite actual number. Amount of 5 and also (-5) is zero.

Therefore, (-5) is additive inverses the 5

or, 5 is additive inverses the (-5).

Property of the opposite of a amount of Addition:

If a and also b are any kind of two totality numbers,then

–(a + b) = (–a) + (–b)

The the contrary of the sum of entirety numbers is equal to the sum of the opposites whole numbers.
