Question 1
1 / -0

Additive inverse of $$(24-(-4))$$ is:

A
$$-28$$

B
$$28$$

C
$$1$$

D
$$0$$

Solution

$$(24-(-4))= 24+4 = 28$$

Let additive inverse of $$28$$ be $$x$$.
Then $$28+x = 0$$
$$\therefore x = -28$$
Question 2
1 / -0

Evaluate:
$$23-(-123)$$

A
$$146$$

B
$$-146$$

C
$$100$$

D
$$-100$$

Solution

Given that
We have to find the value of the given expression
$$23-(-123)$$

we know that $$(-) \times (-) = +$$
and $$(+) \times (-) = -$$
$$=23+123$$
$$=146$$

So option $$A $$ is correct
Question 3
1 / -0

Additive inverse of $$10 $$ is

A
$$0$$

B
$$-10$$

C
$$8$$

D
none

Solution

Let additive inverse of $$10$$ be $$x$$.
$$10+x = 0$$

$$\therefore x = -10$$
Question 4
1 / -0

Evaluate:
$$145-(-89)$$

A
$$234$$

B
$$56$$

C
$$-234$$

D
$$-56$$

Solution

Given that
We have to find the value of given expression
$$145-(-89)$$
we know that $$(-) \times (-) = +$$
and $$(+) \times (-) = -$$
$$=145+89$$
$$=234$$
So option $$A $$ is correct
Question 5
1 / -0

Let the value of $$ A= 5$$ and $$B=9$$
Then the value of $$(-A)+(-B)$$ is

A
$$-14$$

B
$$14$$

C
$$45$$

D
$$-45$$

Solution

To add 2 negative numbers just add the absolute value of each number together, put a negative sign in front
$$(-A)+(-B)=-(A+B)\\ \Rightarrow (-5)+(-9)=-(9+5)=-14$$
Question 6
1 / -0

Solve $$(-24) + (-96) = $$

A
$$-120$$

B
$$96$$

C
$$120$$

D
$$-96$$

Solution

$$(-24) + (-96)$$
$$(-24-96)$$
$$= -120$$
Question 7
1 / -0

The alphabet which has the smallest coordinate in the given figure is.........and its coordinate is ........

A
$$F, 6$$

B
$$S,-4$$

C
$$O,0$$

D
$$A,1$$

Solution

As the coordinates are in increasing order from left to right, leftmost alphabet has smallest coordinate.

Alphabet $$: S$$
Coordinate $$: -4$$
Question 8
1 / -0

The addition of two negative numbers is always a

A
positive number

B
zero

C
negative number

D
none of these

Solution

Addition of two negative number is always negative.
Suppose $$A$$ and $$B $$ are the absolute value of negative number $$-A$$ and $$-B$$, Then the addition number is:
$$(-A)+(-B) =-(A+B)$$ ( Where $$-(A+B)$$ is negative)
Question 9
1 / -0

The coordinate of $$5^{th}$$ alphabet on right of $$O$$ is

A
$$-5$$

B
$$5$$

C
$$4$$

D
$$-4$$

Solution

$$5$$th alphabet to the right of $$O$$ is $$E$$.

$$E$$ lies on $$5$$ on number line. Hence, its coordinate is $$5$$.
Question 10
1 / -0

The coordinate of $$4^{th}$$ alphabet on left of $$B$$ is

A
$$-2$$

B
$$3$$

C
$$2$$

D
$$-1$$

Solution

$$4$$th alphabet to the left of $$B$$ is $$Q$$.

$$Q$$ lies on $$-2$$ on number line. Hence, its coordinate is $$-2$$.
