Is Zero an even number - for the purposes of KeyStage 2 SATS (UK Primary School Yr 6)?
Form the smallest 4 digit number by choosing any three odd and one even digit from the set {7, 5, 2, 1, 0}. What is the correct answer (for SATS purposes) and why? Would the answer be different if the instruction insisted the answer is written out in words?

I know the answers to the mathematical status of zero, which depend on whether in 2N, N is an integer, a counting number, or a natural. In the latter case zero would not be in the set of evens, since zero is not a natural number, in common definitions.) What I'd like to know is which definition is taught in UK Primary Schools. And, as a bonus question, whether a leading zero - as in 0157 - would be considered a correct answer and if it would still be correct if written out in words. And as a bonus bonus, when the question does not explicitly limit you to use each digit only once, whether 0111 would be a valid answer. And as a triple bonus, discuss whether children are well served by questions with so many layers of ambiguity
Answers:
correct. give yourself a smiley face
no because what ever number even or odd you divide/multiply zero by it still becomes zero therefore zero is a number of no mathematical value.
