Answer to Question #3037 in Algebra for Francia

Question

A universe consits of the set of intergers. if subset A consits of the whole numbers, what is the complement of set A?
1) {x|x E nonnegative intergers}
2) {x|x E intergers <1}
3) {x|x E negativie intergers}
4) {x|x E the opposite of the whole numbers}

Answer 1

Integers = { ..., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, ... }
A= { 0, 1, 2, 3, 4, 5, ... }

So ~A= { ..., -5, -4, -3, -2, -1 }
And answer is 3)
~A= {x|x E negativie intergers}
