Lesson 4: Absolute value

# Meaning of absolute value

Absolute value is a fundamental math concept that measures the distance of a number from zero, regardless of its sign. It's always a positive value, as it represents the magnitude of a number without considering its direction. This concept is useful in real-world applications, such as calculating distances and comparing heights. Created by Sal Khan.

• I still do not understand the purpose of absolute value. So far, the examples do not show a need to use this function. No one puts a number line on paper and goes, oh, the school is at 0, and you are at negative three, so absolute value.....bro, you check how far it is.
