QUESTION: 1

−5 × (−6) = ?

Solution:

-5 x -6 = 30  ( because - x - = + ) 

So option D is the correct answer. 

QUESTION: 2

−5 × (6) = ?

Solution:

−5 × (6) = -30 

(Negative sign is because  - x + = - )

So option C is the correct answer. 

QUESTION: 3

−4 × (−7) = ?

Solution:

−4 × (−7) =  -4 x -7   (By BODMAS rule)

                = 28          ( - x - = + )

So option C is correct answer.

QUESTION: 4

−4 × (7)  = ?

Solution:

−4 × (7)  = -28  ( Because  - x + = - )

QUESTION: 5

−45 ÷ 9 = ?

Solution:

−45 ÷ 9 =  -5 

Option C is correct answer. 

QUESTION: 6

10 × (−3) = ?

Solution:

10 × (−3) = -30 ( Because - x + = - )

So option C is the correct answer. 

QUESTION: 7

−45 ÷ (−9) = ?

Solution:

−45 ÷ (−9)  = -45 / -9 = 5   ( Because 9 x 5 = 45 )

So option B is the correct answer. 

QUESTION: 8

−67 × (−1) = ?

Solution:

 -67 x (-1) = 67 ( Because - x - = +)

So option C is the correct answer.

QUESTION: 9

Solution:
QUESTION: 13

At Shimla, temperature was – 5°C on Monday and then it dropped by 2°C on Tuesday. What was the temperature of Shimla on Tuesday?

Solution:

Temperature on Monday = -5°C

Temperature on Tuesday = Temperature on Monday - 2°C

-5°C - 2°C = -7°C

So option A is correct answer. 

QUESTION: 14

6 × (−15 + 10) = ______

Solution:

Firstly, solving the terms inside the bracket, we get -15 + 10 = -5.

Then, multiplying it with 6, we get 30 with '-' sign.

QUESTION: 15

(−4) × (−3) × (−2) = _______

Solution:

(−4) × (−3) × (−2) =  - 4 x 6 = -24 

So option D is correct answer 

QUESTION: 16

-(−2) × (3 + 5) = ________

Solution:

By applying BODMAS rule to the above equation 

-(−2) × (3 + 5) =( 2) x (8) = 16 

QUESTION: 17

(−12 - 3) ÷ (− 6 + 3) = _________

Solution:

Firstly, solving the terms inside the brackets, we get

(−12 - 3) = -15

(− 6 + 3) = -3

So, on diving, the '-' signs get cancelled and we get answer as 5.

QUESTION: 18

If a = 20, b = 40 and c = 80 then a x b + a x c must be equal to

Solution:

Given values are :
a = 20
b = 40 and
c = 80

So a x b + a x c= 20 x 40 + 20 x 80 

= 800 + 1600

= 2400 

So option A is correct answer. 

QUESTION: 19

If a x (b −c) is 8 for a = 2, b = 10 and c = 6 then a x b − a x c is equal to

Solution:

a x b = 2*10 = 20

a x c = 2*6 = 12

So, by using BODMAS,

Ans. = 20 - 12 = 8

QUESTION: 20

The product of -140 and +8 is

Solution:
