Answer:
54
Step-by-step explanation:
Think of the I as a car wash and negative numbers as dirty cars and positive numbers as clean cars, if you put a dirty car in a car wash it will come out clean meaning.....
I-1I = 1
In this case we have positive 54 and if you put a clean car in a car wash it will remain clean therefore....
I54I = 54
= 54
Hope this helps.
