Question 1
1 / -0

The value of $$(-3) +(-11)$$ is

A
$$-33$$

B
$$-8$$

C
$$-11$$

D
$$-14$$

Solution

$$\textbf{Step -1: Calculation}$$
$$\text{Given to calculate :}(-3)+(-11)$$
$$\implies -(3+11)=-14$$
$$\textbf{Hence, option (D) is correct. }$$
Question 2
1 / -0

Which of the following is an example of integer?

A
$$-5$$

B
$$\dfrac{5}{2}$$

C
$$1.4$$

D
$$\dfrac{-7}{2}$$

Solution

$$-5$$ is an integer number.
Question 3
1 / -0

Compare and put the appropriate sign.
$$-219\;\square 212$$..

A
$$\neq$$

B
$$<$$

C
$$>$$

D
$$=$$

Solution

A positive number is always greater than a negative number.
Thus $$-219<212$$.
Question 4
1 / -0

Compare and put the appropriate sign in the box.
$$-210\;\square-211$$.

A
$$<$$

B
$$>$$

C
$$=$$

D
$$\neq$$

Solution

$$210<211\\ \Rightarrow -210>-211$$ put the negative sign both side, < sign will change to > sign.
Question 5
1 / -0

_____________ is neither positive integer nor negative integer.

A
Zero

B
One

C
Two

D
Three

Solution

Zero lies at the centre of Numberline and it is neither positive nor negative.
Question 6
1 / -0

___________ is a bigger number than any negative integers and smaller number than any positive integers.

A
Four

B
Three

C
One

D
Zero

Solution

Zero is a bigger number than any negative integers and smaller number than any positive integers.
Question 7
1 / -0

On a number line, numbers on left side is ____________ numbers on right side.

A
greater than

B
smaller than

C
equal to

D
None of the above

Solution

Numbers are in increasing order from left to right on Numberline.
Question 8
1 / -0

If p: when a positive integer and a negative integer are added we always get a negative integer and q: when two negative integers are added, we get a positive integer, then.

A
Both p and q are true

B
p is true and q is false

C
p is false and q is true

D
Both p and q are false

Solution

When we add positive integer and negative integer then it is not necessary that result would be negative integer. It can be positive integer also
For eg- $$(+8)+(-6)=2$$. Hence the p statement is false.
When we add two negative integers, we will always get negative integer.
For eg- $$(-7)+(-9)=-16$$. Hence q statement is also false
Question 9
1 / -0

Compare and choose the appropriate sign.
$$43,29,52,280$$ $$ \Box$$ $$43,29,25,280$$

A
$$>$$

B
$$<$$

C
$$=$$

D
None of these

Solution

Start comparing with the numbers having greatest place value (from left) till you get an inequality.
$$4=4$$
$$3=3$$
$$2=2$$
$$9=9$$
$$5>2$$
As left value is greater than right value,
the number on the left is greater.
$$\therefore$$ $$43,29,52,280> 43,29,25,280$$
Hence correct answer is option A.
Question 10
1 / -0

Which of the following number line represents $$-1-4$$?

A

B

C

D

Solution

The number line shown above represents $$-1-4$$
In above number line both arrows are going in same direction, means their will be a addition.
First arrow goes $$0$$ to $$-1$$ and second arrow goes from $$-1$$ to $$-5$$.
$$\therefore$$ $$-1+(-4)$$
$$\therefore$$ $$-1-4=-5$$

Hence, option A is correct.
