What is the concept of absolute value in junior high school mathematics
For example, a = 4, B = 5, B < A, try to find the value of B
I didn't understand what the teacher said today

A = 4, indicating that a is equal to + 4 or - 4
B = 5, indicating that B is equal to + 5 or - 5
B < A, so B can only be - 5. A may be 4 or - 4
