Beyond the Answer
The absolute value of a number is simply its distance from zero on the number line, regardless of direction. So, \( |57| = 57 \) because 57 is already a positive number. If the number had been negative, like -57, the absolute value would still be positive: \( |-57| = 57 \). Neat, right? In real-life situations, absolute values can be really handy! For example, if you're measuring temperatures, you can express temperature change without worrying about whether it's above or below freezing. If the temp shifts from -5°C to 5°C, the absolute change is |5 - (-5)| = |10| = 10°C. Handy for avoiding the chills while calculating!
