Let A = {the whole numbers} and B = {the integers}. Find A ∩ B. 0 the integers the whole numbers the real numbers
\[A=\{0,1,2,3,...\}\] \[B=\{...,-3,-2,-1,0,1,2,3,...\}\] What elements are in both sets?
Yes, you definitely need to define "whole numbers" first....
so the bottom one
So you are saying 1/2 is in both sets which is not true 1/2 is real, right? is 1/2 in either of those sets?
Now look at the sets and tell me which elements occur in both of them?
Does -1 occur in both sets?
no zero does
Does 1 also occur in both sets?
So 0,1,2,3,.... are elements that occur in both sets?
yes
which I called what at the beginning? This set {0,1,2,3,...} I called the ___________ ?
If you figure out what set this is then you will have your answer
By the way you can find the answer by scrolling up because I already told you what {0,1,2,3,...} this was called
