Hi there!
absolute value= the opposite of that number if only negative:
Step By Step Explanation:
41-1=40
bring a negative sign if not absolute value.
1+51=52
since it’s already in it’s abolute value it won’t change..
61-1=60
bring a negative sign if nessary..
Therefore, the absolute value for the expression 1-41, 1 +51, 1-61 is 40,52, and 60..
