This is my first Puzzle posting on here. If I can figure out how to do a spoiler, I will add in a hint. Best of luck!
I heard this one a while back, and I don't know how well known it is.
Example 1:
-75 = 19
19 = 8
8 = 5
5 = 4
4 = 4
Example 2:
252 = 18
18 = 8
8 = 5
5 = 4
4 = 4
Figure out the process of how I am go form any number and get it to be 4=4.
Prove that you have figured it out how I am doing it by getting 74 all the way down to 4=4
