4. Say true or false. The absolute value of an integer is always greater than the integer.

Ans: True 


5. The predecessor of\[~\mathbf{219}\] is \[\mathbf{218}\]. Say true or false.

Ans: Predecessor of a number is the one that comes before the number.

\[\begin{align} & \text{Predecessor of a number} \\  & =\text{Number}1 \\  & =\left( -219 \right)1 \\  & =220. \\  \end{align}\]

Hence the statement is false.

Ans: (a) Subtracting $-842$ from $0$,

$\begin{align} & 0-\left( -842 \right) \\  & =0+842 \\  & =842 \\  \end{align}$

Hence, the answer is $842$.

(b) Subtracting $-2959$ from $8158$,

$\begin{align} & 8158-\left( -2959 \right) \\  & =8158+2959 \\  & =11117 \\ \end{align}$

Hence, the answer is $11,117$.


4. The sum of two integers is – 38. If one of them is 240. Find the other.

Ans: We know that, $\text{addend+addend=sum}$

From given,

$\begin{align} & 240+X=-38 \\  & X=-38-240 \\  & X=-278 \\  \end{align}$

Hence, the other number is $-278$.


5. Find the product of \[\left( -27 \right)\times 18\times 30\].

Ans: The product of \[\left( -27 \right)\times 18\times 30\] is

\[\begin{align} & \left( -27 \right)\times 30\times 18 \\  & =-810\times 18 \\  & =-14580 \\  \end{align}\]

Hence, the answer is \[-14,580\].


6. Simplify: $\left( -37 \right)\times \left( -16 \right)+\left( -37 \right)\times \left( -14 \right)$.

Ans: $\left( -37 \right)\times \left( -16 \right)+\left( -37 \right)\times \left( -14 \right)$…(1)

We know that by distributive property,

$a\times b+a\times c=a\times \left( b+c \right)$

Hence, by (1),

$a=-37$, $b=-16$, $c=-14$

We get,

$\begin{align} & \left( -37 \right)\left[ \left( -16 \right)+\left( -14 \right) \right] \\  & =\left( -37 \right)\left[ -30 \right] \\  & =-1110 \\ \end{align}$

The answer after simplification is $-1110$.


7. Divide \[\left( +\mathbf{3251} \right)\] by \[\left( -\mathbf{27} \right)\].

Ans: We know that, 

$\frac{\left( +3251 \right)}{\left( -27 \right)}=-\left( \frac{3251}{27} \right)$

By long division, we get,


Long division of 3251 by -27


Hence, we get,

$\begin{align} & \text{Quotient=-120} \\  & \text{Remainder=11} \\  \end{align}$


4 Marks Questions

1. Using number line, write the following

(a) \[\mathbf{4}\] more than \[\mathbf{6}\]

Number line showing the operation “4 more than 6”


(b) \[\text{5 more than -2}=5+\left( -2 \right)=5-2=3\]


Number line showing the operation “5 more than -2”


(c) $6\text{ less than 4=4-6=-2}$


Number line showing the operation “6 less than 4”


(d)$3\text{ less than }-2=\left( -2 \right)-3=-2-3=-5$


Number line showing the operation “3 less than -2”


2. A bus travelled 30km to south, then 40km to north and from 30km to west. How for did the bus travel?

Ans:


Illustration of the distance of a bus traveled 30km to south, then 40km to north and from 30km to west


Distance travelled south = \[-30\]km

Distance travelled North = \[40\]km

Distance travelled West = $-30$km

Hence, Total distance travelled 

\[\begin{array}{*{35}{l}} =\left( -30 \right)+40+\left( 30 \right)  \\ \begin{align} & =60+40 \\  & =-20 \\  \end{align}  \\ \end{array}\]

Thus, the total distance travelled is $20$km towards the south.


5 Marks Questions

1. In a class test containing \[\mathbf{25}\] questions, \[\mathbf{4}\] marks are given for every correct answer and \[\left( \mathbf{2} \right)\] marks are given for every wrong answer. A student attempts all questions and \[\mathbf{20}\] of his answers are correct. What is the total score of a student?

Ans: Total questions in test \[=25\]

Marks are given for 1 correct answer \[=4\]

Marks are given for 1 incorrect answer \[=2\]

Marks given for 20 correct answers \[=20\times 4=80\]

Total incorrect answers \[=\left( 2520 \right)=5\]

Marks given for incorrect answers \[=5\times \left( 2 \right)=10\]

Total score in test 

\[\begin{align} & =80+\left( 10 \right) \\  & =70 \\  \end{align}\]

Hence, the total score in the test is $70$ marks.

Let’s Revise

  • Integers is a set of all natural numbers, 0 and negatives of natural numbers are called integers, i.e., we can represent the integers on the number line. 

  • Integers range from { ………, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, …….. }

  • The absolute value of an integer is the numerical value of the integer in any case regardless of its sign.

  • Successors and predecessor of an integer: Let abe an integer, then: 

(a + 1) is called the successor of a.

(a - 1) is called the predecessor of a.

  • Properties of addition of integers:

(i) Closure property of addition: The total of two integers is always an integer.

(ii) Commutative law of addition: a + b = b + a

(iii) Associative law of addition: the sum remains the same even if the grouping of addends change.

  • Properties of subtraction of integers: 

(i) If two integers a and b are given then (a - b) is also an integer.

(ii) If a is considered an integer, then a - 0 = a.

(iii) if a, b, c are integers and a>b, then (a - c)>(b - c)

  • Properties of multiplication of integers:

(i) Closure property: The result of two integers is always an integer after multiplication.

(ii) Commutative law: a x b = b x a.

(iii) Associative law: a x (b x c) = (a x b) x c.

(iv) Distributive law: a x (b + c) = a x b + a x c.

  • Properties of division of integers:

(i) If two integers are a and b, then a ÷ b is not necessarily an integer.

(ii) If a ≠ 0, then a ÷ a = 1 

(iii) a ÷ 1 = a.

(iv) If a is a non-zero integer, then 0 ÷ a = 0, but  a ÷ 0 is not meaningful.

(v) (a ÷ b) ÷ c ≠ a ÷ (b ÷ c) unless c = 1.

  • Representation of Integers on Number line: To represent integers on a number line, draw a line and mark some points at equal distances on it. Mark a point as 0 on it. Points to the right of 0 are positive integers and are marked as +1, +2, +3, etc. or simply 1, 2, 3, etc. Points to the left of are negative integers and are marked as -1, -2, -3, etc. 

  • Ordering of Integers: On the number line, integers are grouped in such a way that when we move to the right the numbers increase and when we move to the left, the numbers decrease.

  • We add the corresponding positive integers and retain the negative sign with the sum when adding two negative integers, Ex: Find the sum of -3 and -3. 

-3 + (-3) = - (3+ 3) = -6.

To add a positive integer and a negative integer, we ignore the signs and subtract integers with smaller numerical value from the integer with a larger numerical value and take the sign of the larger one. 

Ex: (a) Consider -6 and + 4

As 6 -4 = 2, therefore -6 + (+4) = -2

(b) Consider + 5 and -2

5 + (-2) = 5 - 2 = 3

Two integers whose sum is 0 are called additive inverse of each other. 

In order to subtract an integer from a given integer, we add an additive opposite of the integer to the given integer.

Ex: (a) Subtract 3 from -4

The additive inverse of 3 is -3

So, -4, -3 = -4 + (-3) = (4 + 3) = -7

(b) -2 from -4

The additive inverse of -3 is 3

So, -4 - (-2) = -4 + 2 = -2

  • Addition/ Subtraction of Integers on Number line: Firstly draw the number line and represent the first number on it. Then to add/ subtract the second number in first, we move left/ right to the first number according to the second integer (either -ve or +ve)
