A number's distance from zero on the number line, always non-negative.
It's the positive version of that number - |−7| = 7.
Zero, since zero's distance from itself is zero.
No, absolute value is always zero or positive by definition.
Using vertical bars around the number, like |x|.
No, calculations happen entirely in your browser.
Distance calculations, error margins, and magnitude comparisons all use absolute value.
No, the absolute value of a positive number is the same number.
Yes, absolute value is often used when only magnitude matters, not direction.
