Which of these numbers has the largest absolute value?

1. Absolute value is distance from zero, so the sign is ignored when comparing. 2. The distances here are 9, 5, 3 and 1. 3. The largest of those distances is 9, belonging to negative 9. 4. A negative number can therefore have a larger absolute value than a positive one. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 3 "Integers", section Absolute Value_
