The additive identity for integers is:

- a)0
- b)-1
- c)1
- d)None of these

Correct answer is option 'A'. Can you explain this answer?

Gunjan Lakhani answered • 2 hours ago

- The
**additive identity property**says that if you add an integer to zero or add zero to the integer, then you get the same integer back. - So,
**zero (0)**is the additive identity for integers, i.e., a + 0 = 0 + a = a.

The product of three negative integers is:

- a)a positive integer
- b)either a positive integer or a negative integer
- c)a negative integer
- d)none of these

Correct answer is option 'C'. Can you explain this answer?

If the number of negative integers in a product is **odd**, then the product is a **negative integer**.

The value of [(-4) x (-9) x (-25)] ÷ [(-2) x (-3) x (-5)] is:

- a)30
- b)20
- c)10
- d)40

Correct answer is option 'A'. Can you explain this answer?

Gunjan Lakhani answered • 2 hours ago

- Firstly we will solve brackets according to
**BODMAS**rule,

(-4) x (-9) x (-25) = -900 (multiplication of odd number of negative integers gives a negative integer)

(-2) x (-3) x (-5) = -30 (-900) / (-30) = 30 (division of even number of integers gives a positive integer)

The sum of two integers is -112. If one of them is -109 the other is:

- a)-121
- b)3
- c)-3
- d)None of these

Correct answer is option 'C'. Can you explain this answer?

Gunjan Lakhani answered • 2 hours ago

► x + (-109) = -112

► x = -112 + 109

► x = -3

► x = -112 + 109

► x = -3

a × (b + c) = a × b + a × c is called ______.

- a)Distributive property
- b)Associative property
- c)Commutative property
- d)Closure property

Correct answer is option 'A'. Can you explain this answer?

Gunjan Lakhani answered • 2 hours ago

- The
**distributive property**lets you multiply a sum by multiplying each addend separately and then add the products. - Mathematically it can be written as:

a × (b + c) = a × b + a × c

Which of the following is true?

- a)(- 8) + (- 4) > (- 8) – (- 4)
- b)(-8) + (- 4) = (- 8) – (- 4)
- c)(- 8) + (- 4) < (- 8) – (- 4)
- d)None of these

Correct answer is option 'C'. Can you explain this answer?

Gunjan Lakhani answered • 2 hours ago

(- 8) + (- 4) < (- 8) – (- 4)

► (-8) + (-4) = -12

► (-8) – (-4) = -4

Therefore, -12 < -4

► (-8) + (-4) = -12

► (-8) – (-4) = -4

Therefore, -12 < -4

A place is 45 metre above sea level and another place is 25 meter below sea level. What is the difference of level in metres between the two places?

- a)60
- b)20
- c)70
- d)-20

Correct answer is option 'C'. Can you explain this answer?

Gunjan Lakhani answered • 2 hours ago

45 m above sea level = +45

25 m below sea level = -25

Therefore, 45 - (-25) = 70

25 m below sea level = -25

Therefore, 45 - (-25) = 70

Difference between 43°C and -17°C is:

- a)-26°C
- b)60°C
- c)-60°C
- d)26°C

Correct answer is option 'B'. Can you explain this answer?
