#### Integers Questions For Class 6 – Successor of an Integers

The successor of any number (including Integers ) will be the number which is 1 greater than the number, or comes after that number in number line.

**Example 1**

The successor of given integer 639 is ?

The successor of any number (including Integers ) will be the number which is 1 greater than the number, or comes after that number in number line

So, we have to add 1 to the integer to find its successor.

In present case,

639 + 1 = 640

So, the successor of 639 is 640

**Example 2**

The successor of given integer -538 is ?

The successor of any number (including Integers ) will be the number which is 1 greater than the number, or comes after that number in number line

So, we have to add 1 to the integer to find its successor.

In present case,

-538 + 1 = -537

So, the successor of -538 is -537

#### Integers Questions For Class 6 – Predecessor of an Integers

The predecessor of any number (including integers) will be the number which is one lesser than the number, or comes before than that number in number line

**Example 3**

The predecessor of given integer 1639 ?

The predecessor of any number (including integers) will be the number which is one lesser than the number, or comes before than that number in number line

So, we have to subtract 1 from the given integer to find its predecessor.

1639 – 1 = 1638

So, the predecessor of 1639 is 1638

**Example 4**

The predecessor of given integer -582 ?

The predecessor of any number (including integers) will be the number which is one lesser than the number, or comes before than that number in number line

So, we have to subtract 1 from the given integer to find its predecessor.

-582 – 1 = -583

So, the predecessor of -552 is -583

**Integers Questions For Class 6 – Addition of Integers**

**Rule 1** – While adding two integers with the same sign, we add their values regardless of their signs, and give the sum, their common sign.

**Rule 2** – When we have to add two integers with different signs ( one is positive and other is negative), we find their difference, regardless of their signs, and give the sign of the integer with the greater value to such difference.

**Example 5**

Find the sum of 25 and 27?

**Explanation**

While adding two integers with the same sign, we add their values regardless of their signs, and give the sum, their common sign.

In present case,

First, we add the values of the two integers, regardless of the negative sign:

25 + 27 = 52

Now we would assign the common sign to the answer,

In present case the common sign is ( + )

So, the sum of 25 and 27 is +52 or 52

**Example 6**

Find the sum of (-47) and (-52)?

**Explanation**

While adding two integers with the same sign, we add their values regardless of their signs, and give the sum, their common sign.

In present case,

First, we add the values of the two integers, regardless of the negative sign:

47 + 52 = 99

Now we would assign the common sign to the answer,

In present case the common sign is ( – )

So, the sum of (-47) and (-52) is -99

**Example 7**

Find the sum of 68 and -32?

**Explanation**

When we have to add two integers with different signs ( one is positive and other is negative), we find their difference, regardless of their signs, and give the sign of the integer with the greater value to such difference.

In present case,

First we find the difference to the given integers i.e, 68 – 32 = 36

Now, we would assign the sign of the greater integer to the result.

In this case, 68 > 32

and the sign of 68 is ( + )

Hence, the sum of 68 and -32 is +36 or, 36

**Example 8**

Find the sum of -17 and 25?

**Explanation**

When we have to add two integers with different signs ( one is positive and other is negative), we find their difference, regardless of their signs, and give the sign of the integer with the greater value to such difference.

In present case,

First, we find the difference to the given integers i.e, 25 – 17 = 8

Now, we would assign the sign of the greater integer to the result.

In this case, 25 > 17

and the sign of 25 is ( + )

Hence, the sum of -17 and 25 is +8 or, 8

#### Integers Questions For Class 6 – Subtracting Integers

**Example 9**

Subtract:

64 – 50

**Explanation**

In order to subtract a smaller integer from a larger integer, where both the integers are positive, we subtract the smaller integer from the higher integer, and give the positive sign to the difference.

So, first we subtract the smaller integer from the higher integer.

64 – 50 = 14

Now, we assign positive sign to the result i.e, +14 or 14

Hence, 64 – 50 = 14

**Example 10**

Subtract:

53 – 79

**Explanation**

In order to subtract a larger integer from a smaller integer, where both the integers are positive, we subtract the smaller integer from the higher integer, and give the negative sign to the difference.

So, first we subtract the smaller integer from the higher integer.

79 – 53 = 26

Now, we assign negative sign to the result i.e, -26

Hence, 53 – 79 = -26

**Example 11**

Subtract:

( -31 ) – ( -15 )

**Explanation **

In order to subtract a smaller integer from a larger integer, where both the integers are negative, we subtract the smaller integer from the higher integer, and give the negative sign to the difference.

In the present case, both – 31 and – 15 are negative.

Difference of the two integers, ignoring their signs :

= 31 – 15

= 16

Now, we assign negative sign to the result i.e, (-16)

Hence, ( -31 ) – ( -15 ) = (-16)

**Example 12**

Subtract:

( -19 ) – ( -34 )

**Explanation**

In order to subtract a larger integer from a smaller integer, where both the integers are negative, we subtract the smaller integer from the higher integer, and give the positive sign to the difference.

In the present case, both – 19 and – 34 are negative.

Difference of the two integers, ignoring their signs :

= 34 – 19

= 15

Now, we assign positive sign to the result i.e, (+15)

Hence, ( -19 ) – ( -34 ) = (+15) or 15

**Example 13**

Subtract:

( 7 ) – ( -13 )

**Explanation**

When we subtract a negative integer from a positive integer then, we add the two numbers.

Since, 7 is positive and 13 is negative

We simply Add the two integers, ignoring their signs:

= 13 + 7

= 20 or +20

Hence, ( 7 ) – ( -13 ) = +20 or 20

**Example 14**

Subtract:

( – 59 ) – ( 81 )

When we subtract a positive integer from a negative integer, we add the two integers and and give the negative sign to it.

Since, – 59 is negative and 81 is positive

We simply Add the two integers, ignoring their signs:

= 81 + 59

= 140

and assign negative sign to the result i.e, -140

Hence, ( -81 ) – ( 59 ) = -140

#### Integers Questions For Class 6 – Multiplication of Integers

**Rule 1 – **In order to find the product of two integers with same signs, we simply multiply the integers regardless of their signs and give a ( + ) positive sign to the product.

**Rule 2 – **In order to find the product of two integers with different signs, we simply multiply the integers regardless of their signs and give a ( – ) negative sign to the product.
