This I know … that zero is even :wink:

However there seems to be conflicting opinions on the question, if zero can be squared. Thus, most say it is zero, while some say it is without result.

Have a good day :slightly_smiling_face:

Now I finally got it.
0² must be zero, since a square with two sides of a length of zero has a size of zero.
Thanks for making me rethink the topic :+1:

  1. A function is an equation, where a variable set in an input results in an output that changes depending on the variable input.

a) f(2)= 2^2 = 4 (is even)

b) f(7) = 7+10 = 17 (is odd)

c) f(0)= 0 (is even, parity of zero, bless zero :D)

  1. f(x) = (x/4) - 5
