Question

Evaluate: I -8 I – I 6 I​

Answer 1

Answer:

-2

Step-by-step explanation:

|-8| - |-6|= -8+6=(-+=-)=-2

Answer 2

Answer:

|-8| - |6| = 2

Step-by-step explanation:

We have,

|-8| - |6|

Now, we must know that,

|a| = { -a when a < 0

a when a > 0

It is called the absolute value, that is, no matter what, the value will always be positive.

Now,

Don't get confused on -a, let me give an example.

Let's say a = (-1)

Then,

|a| = |(-1)| = 1

But we got 1 from (-1) because we took the negative of (-1) That is,

|a| = |(-1)|

= -(-1)

= 1

So, if 'a' takes a negative value, then we take it's negative, and if 'a' takes a positive value, absolute value will be the same.

Now, back to our Question,

I-8I - I6I

Then,

|-8| = 8

|6| = 6

So,

|-8| - |6| = 8 - 6

= 2

Hence,

|-8| - |6| = 2
