You posted in a public Q&A session,
can you tell me which page you are stuck at?
meanwhile, let me go into the lessons and check what might be troubling you.
Ok, I get your problems now
7%(5//2) and (1+?)**2=16
For (1+?)**2=16
** is "to the power of"
for example, 3**2 returns 3*3=9, 2**3 returns 2*2*2=8
so answer is 3
(1+3)**2=4**2=4*4=16
For 7%(5//2)
5//2 is get quotient,
because 5 = 2*2+1, quotient is 2
then 7%2 is get remainder
because 7=2*3+1, remainder is 1
so answer is 1

Answer 2

check this.
