Hello I wonder if someone can help me understand how python comes up with the answer 6 to this script

v=2

w=3

x=4

y=19

z=23

a=v**v//x%x+y%w*z//x

what is going on here, the way I see it, v**v is exponent and done first so that’s four.

then I am not sure what to do, if you do x%x which is the remainder of 4/4 that is zero. so I end up with four // 0 which is not possible
