|a| means the modulus, or positive value of a.
For example |-45| = 45, also |45| = 45
So for your question, 15-23 = -8, so |15-23| = |-8| = 8
For example |-45| = 45, also |45| = 45
So for your question, 15-23 = -8, so |15-23| = |-8| = 8

you just do 15-23 which is -8. l-8l just means how far away is it from 0, and its 8. same thing if the number is positive. (the answer is 8)

you dont have to change anything in this one cuz it dont have = or <
