Weekly Quiz Competition

Question 1
1 / -0

Calculate:
$$9-(-6)$$

A
$$3$$

B
$$-3$$

C
$$15$$

D
$$-15$$

Solution

Given that
We have to find the value of given expression
$$9-(-6)$$
we know that $$(-) \times (-) = +$$
$$9+6$$
$$ = 15$$
So option $$C$$ is correct
Question 2
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 3
1 / -0

Evaluate:
$$145-(-89)$$

A
$$234$$

B
$$56$$

C
$$-234$$

D
$$-56$$

Solution

Given that
We have to find the value of given expression
$$145-(-89)$$
we know that $$(-) \times (-) = +$$
and $$(+) \times (-) = -$$
$$=145+89$$
$$=234$$
So option $$A $$ is correct
Question 4
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 5
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 6
1 / -0

$$1\times 0=$$

A
$$1$$

B
$$0$$

C
$$2$$

D
$$10$$

Solution

The multiplicative identity property states that any time you multiply an integer by $$1$$, the result, or product, is that original number.

To write out this property using variables, we can say that $$n\times 1 = n$$. It doesn't matter if $$n$$ equals to one, one million or $$3.566879$$. The property always hold true. Let us take an integer $$0$$ then,

$$0\times 1=1\times 0=0$$

Hence, $$1\times 0=0$$.
Question 7
1 / -0

For any integer $$a$$, $$a+0=$$

A
$$1$$

B
$$2$$

C
$$a$$

D
$$0$$

Solution

The additive identity property says that if you add an integer to zero or add zero to an integer, then you get the same integer back. The number zero is known as the identity element, or the additive identity. For example, for any integer $$a$$,

$$a + 0 = 0 + a = a$$

Hence, for any integer $$a$$, $$a+0=a$$.
Question 8
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 9
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 10
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 $$x$$.
$$2+x = 0$$

$$\therefore x = -2$$
