Examples
“The absolute value of -5 is 5.”
“When calculating the total distance moved, you must use the absolute value of each step so that backward movements don't cancel out forward ones.”
“The function is defined such that the output always corresponds to the absolute value of the input, ensuring a non-negative result across the entire domain.”
