Question

i will give medal

Answer 1

\[A=\left\{ 0,1,2,3,... \right\}B=\left\{ 0,\pm1,\pm2,\pm3,... \right\}\]

Answer 2

what is A intersection B and B intersection A

Answer 3

So tell me what A intersect B is asking you to find?

Answer 4

i dont understand this because the set is endless

Answer 5

its like 0,1,2,3,.... and so on

Answer 6

Both sets are endless but you can assume A is going to be all whole numbers, meaning \[0 \to \infty\]
While we can assume B is going to be all integers, meaning \[-\infty \to \infty\]

Answer 7

So the intersection would be all numbers that are in both sets, which would be?

Answer 8

A-B={ }
B-A={0,1,2,3,...}

Answer 9

Are you finding intersect or A-B, B-A?

Answer 10

A int B and B int A are both A here, which is the set of all whole numbers

Answer 11

hint:
A is a subset of the set B

Answer 12

furthermore, we have:
\[\large A \cap B = B \cap A\]
