|0 - 6|
|-2| · |3|

Answer 1

expect 2 and 3 all are equal to 6

Answer 2

Hey there !

Concept:

Any negative number inside a modulus is always a positive number and any positive number inside a modulus function is also always a positive number.

A negative sign outside modulus function doesn't affect the equation. It will always be a negative number.

Hence the solutions are as follows:

1) I 6 I = 6

2) I -6 I = 6

3) - I 6 I = - 6

4) - I -6 I = - 6

5) I 0 - 6 I = I -6 I = 6

6) I -2 I . I 3 I = 2 . 3 = 6

Hope my answer helped !
