so '*' here means '32 -' ? I found this kinda confusing

This is known as a Strange Operator question (see video below)

For this question, the asterisk symbol (*) tells us to take whatever number is next to it and subtract it from 32. That is, *n = 32 - n

So, for example, *10 = 32 - 10 = 22 And *15 = 32 - 15 = 17 And *100 = 32 - 100 = -68

------NOW ONTO THE QUESTION------------

Quantity A: (n*)* Quantity B: n

Let's simplify (n*)* First off, n* = 32 - n So, (n*)* = (32 - n)*

Now let's simplify (32 - n)* (32 - n)* = 32 - (32 - n) = n

So, we have: Quantity A: n Quantity B: n

Answer: C
