All of the following expressions are equal to N except . −(− N) − N | N| |− N|

-N

Step-by-step explanation:

Given expressions are:

-(-N)

-N

|N|

|-N|

To find: Which of the given expressions are not equal to N.

Solution:

Let us consider and solve each expression one by one:

-(-N)

Negative of negative becomes positive.

In the given expression, same thing is done so negative of negative gives us a positive result.

-(-N) is equal to N

-N

Negative of N can not be equal to N.

|N|

First of all, let us learn about modulus / absolute function.

Absolute function always gives us positive result even if there is a negative sign inside the expression.

So, |N| is equal to N.

|-N|

As explained above, result from modulus/absolute function comes out to be positive.

So, |-N| is equal to N.

Hence, the answer is -N.

the correct answer is c
