Question 1
1 / -0

Calculate $$-98-56=?$$

A
$$-154$$

B
$$154$$

C
$$42$$

D
$$-42$$

Solution

Given that
We have to find the value of given expression
$$-98-56$$
we know that $$(-) \times (-) = +$$
and $$(+) \times (-) = -$$
$$-98-56$$
$$ = -154$$
So option $$A$$ is correct
Question 2
1 / -0

Obtain the following:
$$-101-(-200)$$

A
$$99$$

B
$$-99$$

C
$$-101$$

D
$$101$$

Solution

Given that
We have to find the value of given expression

$$-101-(-200)$$

we know that $$(-) \times (-) = +$$

$$-101+200$$

$$=99$$
So option $$C$$ is correct
Question 3
1 / -0

Calculate: $$-46-(-67)$$

A
$$21$$

B
$$-21$$

C
$$22$$

D
$$46$$

Solution

Given that
We have to find the value of given expression
$$-46-(-67)$$
we know that $$(-) \times (-) = +$$
and $$(+) \times (-) = -$$
$$=-46+67$$
$$ = 21$$
So option $$A$$ is correct
Question 4
1 / -0

Calculate:
$$34-(-98)$$

A
$$132$$

B
$$64$$

C
$$-64$$

D
$$-132$$

Solution

Given that
We have to find the value of given expression
$$34-(-98)$$
we know that $$(-) \times (-) = +$$
$$34+98$$
$$ = 132$$
So option $$A$$ is correct
Question 5
1 / -0

Addition of integer and its additive inverse is

A
zero

B
double the number

C
half the number

D
none of these

Solution

Additive inverse of an integer is a number which is of opposite sign and when added to the integer, gives zero.
Thus, Addition of integer and its additive inverse is Zero.
Question 6
1 / -0

Evaluate:
$$133-(-23)$$

A
$$156$$

B
$$136$$

C
$$-156$$

D
$$-136$$

Solution

Given that
We have to find the value of given expression
$$133-(-23)$$
we know that $$(-) \times (-) = +$$
and $$(+) \times (-) = -$$
$$=133+23$$
$$=156$$
So option $$A $$ is correct
Question 7
1 / -0

Additive inverse of $$4\times (-5)$$ is

A
$$-20$$

B
$$20$$

C
$$4$$

D
$$1$$

Solution

$$4\times (-5) = -20$$

Let additive inverse of $$-20$$ be $$x$$.
$$-20+x = 0$$

$$\therefore x = 20$$
Question 8
1 / -0

The additive inverse of $$(-9+11)$$ is :

A
$$-2$$

B
$$3$$

C
$$9$$

D
$$-11$$

Solution

$$(-9 + 11) = 2$$

Additive inverse of a number is that number which when added to the original number, results in the sum as zero.

Let additive inverse of $$2$$ be $$x$$.
$$2+x = 0$$

$$\therefore x = -2$$
Question 9
1 / -0

Evaluate:
$$144-(-44)$$

A
$$-188$$

B
$$100$$

C
$$-100$$

D
$$188$$

Solution

Given that
We have to find the value of given expression
$$144-(-44)$$
we know that $$(-) \times (-) = +$$
and $$(+) \times (-) = -$$
$$=144+44$$
$$ = 188$$
So option $$D $$ is correct
Question 10
1 / -0

Find additive inverse of $$-7$$

A
$$-7$$

B
$$0$$

C
$$7$$

D
$$6$$

Solution

Let additive inverse of $$-7$$ be $$x$$.

$$\Rightarrow -7+x = 0$$

$$\therefore\ x = 7$$

Hence the additive inverse of $$-7$$ is $$7$$
