Answer:

Ι-3Ι = 3

Step-by-step explanation:

We need to evaluate the Ι-3Ι.

In mathematics, when we find the absolute value or modulus  IxI is a non negative value of x without any sign.

The absolute value of x is thus always either positive or zero, but never negative: when x itself is negative (x < 0), then its absolute value is necessarily positive.

For example:

I-xI = x

IxI = x

I-2I = 2

I2I = 2

Similarly,

I-3I = 3

That's the final answer.
