Question 1
1 / -0

Evaluate:
$$(+48) + (-53)$$

A
+5

B
-5

C
5

D
none of these

Solution

$$(+48) + (-53) = 53 -48 = -5$$
Question 2
1 / -0

Subtract $$(-26)$$ from $$32$$.

A
$$-6$$

B
$$+6$$

C
$$-58$$

D
$$+58$$

Solution

To find: $$+32 - (-26)$$
$$ = 32 + 26 = +58$$
Question 3
1 / -0

Multiplication of a negative integer for even number of times gives a _________ number.

A
negative

B
0

C
positive

D
none of these

Solution

Observe $$-1 \times -1 =1$$
Product of a pair of negative numbers is positive.
When even number of negative numbers are multiplied, the result is a positive number because every pair of negative terms will give a positive number.
Question 4
1 / -0

Fill in the blank:
$$68$$ $$\times$$ ____ $$= -68$$

A
0

B
1

C
-1

D
None of these

Solution

$$68 \times (-1) = -68$$
Question 5
1 / -0

Subtract $$-28$$ from $$-12$$.

A
$$-16$$

B
$$+16$$

C
$$+40$$

D
$$-40$$

Solution

Given integers are $$-28$$ and $$-12$$.
To find out: The result when we subtract $$-28$$ from $$-12$$.

Let's perform the subtraction:
$$-12-(-28)$$
$$\Rightarrow -12+28$$
$$\Rightarrow +16$$

$$\therefore \ $$ The result when we subtract $$-28$$ from $$-12$$ is $$+16$$.

Hence, option B is correct.
Question 6
1 / -0

(-12) $$\times$$ (-3) $$\times$$ (+4) $$\times$$ (-6) =

A
-144

B
-908

C
+864

D
-864

Solution

$$\textbf{Step 1: Multiplying them in pairs.}$$

$$\text{There are 3 negative signs. So, the resultant of }3$$ $$\text{multiplications would be negative.}$$

$$\text{Consider, }$$

$$(-12) \times (-3) \times(+4) \times (-6) = (-12\times -3)\times (4\times -6)$$

$$=36\times (-24)$$

$$=-864$$

$$\textbf{Hence, Option D is correct.}$$
Question 7
1 / -0

Fill in the blank:
$$-112$$ $$\times$$ _______ $$= +112$$

A
+1

B
0

C
-1

D
+112

Solution

$$-112 \times (-1) = +112$$
Question 8
1 / -0

Multiplying a negative integer for odd number of times gives a _______number.

A
positive

B
negative

C
0

D
none of these

Solution

(-1) $$\times$$ (-1) $$\times$$ (-I) ......odd times = Negative sign
Question 9
1 / -0

Evaluate:
$$(-46) + (+15)$$

A
$$+31$$

B
$$32$$

C
$$-31$$

D
none of these

Solution

One negative and one positive number are added by doing subtraction of digits and keeping the bigger addend sign to the result.$$(-46) +(+15) =-46+15=-31$$
Bigger addend is 46 with -sign.
$$\therefore$$ -sign is given for the result.
Question 10
1 / -0

$$(+13)+(-12) $$ is equal to

A
+1

B
+ 13

C
- 1

D
None of these
