QUESTION: 1

Which integer is greater than –5?

Solution:

An **integer** on the horizontal **number line** is greater than the **number** on its **left** and less than the number on its right. Therefore, the smallest negative integer is the biggest one.

So -1 will be greater than -5. Thus, option **B** is the correct answer.

QUESTION: 2

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:

Using **BODMAS**,

a x (b − c) = a x b - a x c

= (a x b) - (a x c)

= (2 x 10) - (2 x 6)

= 20 - 12

= 8

So,** option D** is the correct answer.

QUESTION: 3

The product of three negative integers is:

Solution:

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

QUESTION: 4

The additive identity for integers is:

Solution:

- 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.

QUESTION: 5

According to Distributive Law of Multiplication over Addition, a x (b + c) must be equal to:

Solution:

__According to Distributive Law of Multiplication over Addition:__

a x (b + c) = a x b + a x c

QUESTION: 6

Which amongst the following is the largest?

I-89I, -89, -21, I-21I

Solution:

**|x|**gives the absolute value of x. The**absolute value**of any number is the**magnitude**of the real number**without regard to its sign**. The magnitude of a number is its size.- I-89I = 89

I-21I = 21

So,**89 is the greatest**among the given numbers.

QUESTION: 7

The multiplicative identity for integers is:

Solution:

- The
**multiplicative identity**of any integer p is a number q which when multiplied with p, leaves it unchanged, i.e. q is called the multiplicative identity of any integer p, if**p × q = p.** - Now, when we multiply 1 with an integer p we get:

p × 1 = p = 1 × p - So,
**1 is the multiplicative identity for integers**.

QUESTION: 8

What will be the additive inverse of 7?

Solution:

- The
**additive inverse**of a number a is the number that, when added to a, gives zero. This number is also known as the opposite number. - So, when -7 is added to 7 it gives 0.

-7 + 7 = 0 - Thus,
**-7**is the additive inverse of 7.

QUESTION: 9

How many integers are there between -8 and 2 (excluding -8 and 2)?

Solution:

__The integers between -8 & 2 are:__

-7 , -6 , -5 , -4 , -3 , -2 , -1 , 0 , 1- There are
**9 integers**between -8 & 2.

So,**option D**is correct.

QUESTION: 10

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

Solution:

- 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)
