What is the reason that absolute value is always written as a positive?

The distance of any number from the origin on the number line is the absolute value of that number. It also shows the polarity of the number whether it is positive or negative. It can be negative ever a s it shows the distance and the distance can't be negative. So, it is always positive.

Is absolute value always positive yes or no?

The absolute value of a number is always positive or zero. If the original number is negative, its absolute value is that number without the negative sign.

Why is signal power important in communication?

The goal is for the transmitted signal to be of higher power than the interferences, or noise. This makes it easier for people to communicate and understand messages without static, cutting-out, etc.

What is the absolute value of 10?

In the case of the absolute value of 10, or |10|, we have that 10 is positive, so the absolute value of 10 is 10. Geometrically speaking, we define the absolute value of a number x as the distance x is from 0 on the number line.
