Question 1
1 / -0

$$-12- (-5) = ?$$

A
$$-17$$

B
$$-7$$

C
$$7$$

D
None of these

Solution

$$\textbf{Step-1: Simplification}$$
$$-12-(-5)=?$$
$$\text{We know that}$$ $$(-)\times (-)=+$$
$$\text{Hence, we get}$$ $$-12+5$$
$$\textbf{Step-2: Solving}$$
$$-12+5=5-12$$
$$=-7$$

$$\textbf{Hence , the correct option is (B).}$$
Question 2
1 / -0

Mark against the correct answer in the following:
On subtracting -8 from -13, we get

A
-21

B
21

C
5

D
-5

Solution

To get the required value, we subtract $$-8$$ from $$-13$$
$$=-13-(-8)$$
$$=-13+8$$
$$=-5$$
Question 3
1 / -0

Find the value of:
$$(-8) + (-9) $$

A
$$ 18 $$

B
$$ -18 $$

C
$$ 16 $$

D
$$ -17 $$

Solution

Given: $$(-8) + (-9)$$
$$=-8-9$$
$$= -17$$
Question 4
1 / -0

Answer the following using number line.
The integer which is $$ 7 $$ more than $$ -4 $$ is

A
$$ -7 $$

B
$$ -3 $$

C
$$ 3 $$

D
$$ 7 $$

Solution

Starting from $$-4$$, move $$7$$ unit right. So, from the above figure, we can conclude that integer $$ 3$$ is $$7$$ more than $$ -4 .$$
Question 5
1 / -0

The greater integer lying between $$-10$$ and $$-15$$ is

A
$$-10$$

B
$$- 11$$

C
$$-14$$

D
$$-15$$

Solution

Option $$B$$ is right.
$$-11$$ is the greatest integer lying between $$-10$$ and $$-15$$.
Question 6
1 / -0

On subtracting $$ -7 $$ from $$ -4 $$ , we get

A
$$ 3 $$

B
$$ -3 $$

C
$$ -11 $$

D
None of these

Solution

$$\begin{aligned}{} - 4 - ( - 7) &= - 4 + 7\\ &= 3\end{aligned}$$

Hence, if $$-7$$ is subtracted from $$-4$$ then we get $$3.$$
Question 7
1 / -0

The least integer lying between $$-10$$ and $$-15$$ is

A
$$-10$$

B
$$-11$$

C
$$-14$$

D
$$-15$$

Solution

Option $$C$$ is right.
$$-14$$ is the greatest integer lying between $$-10$$ and $$-15$$.
Question 8
1 / -0

The integer with a negative sign $$(-)$$ is always less than

A
$$0$$

B
$$-3$$

C
$$-1$$

D
$$-2$$

Solution

Option $$A$$ is right.
Infact all the negative integers are less than zero.
Question 9
1 / -0

The predecessor of the integer $$-1$$ is

A
$$0$$

B
$$2$$

C
$$-2$$

D
$$1$$

Solution

The predecessor of integer $$n$$ is given by $$n-1$$.
Hence, the predecessor of $$-1$$ is $$(-1 - 1) = -2$$.
Question 10
1 / -0

On the number line, the integer 5 is located _______.

A
to the left of $$0$$

B
to the right of $$0$$

C
to the left of $$1$$

D
to the left of $$-2$$

Solution

The number line represents all the real numbers. The positive numbers are on the right of $$0$$ and the negative numbers are on the left of $$0$$, as shown in the above figure.

Since $$5$$ is a positive number, it lies to the right of $$0$$.

Hence, on the number line, the integer $$5$$ is located to the right of $$0$$.
