## dmezzullo 3 years ago Find A intersection B. A: {2, 4, 6, 8, 10, 12} B: {−2, −1, 2, 4, 7, 11} {−2, −1, 2, 4, 6, 7, 8, 10, 11, 12} {1, 4, 7, 11} {2, 4} { }

A intersection B.={elements common to both A and B} Can u find it @dmezzullo?

3. dmezzullo

no

4. ajprincess

What are the elements in A that are also in B?

5. ajprincess

Are there any such elements?

Can you TRY to learn? :/ A: {2, 4, 6, 8, 10, 12} B: {−2, −1, 2, 4, 7, 11} What numbers can you see in Set A AND Set B?

7. freewilly922

Maybe a visual? |dw:1353338898047:dw|

8. amistre64

if you write it such that like numbers in each set line up, it might be simpler to see

9. amistre64

A: { 2, 4, 6, 8, 10, 12} B: {−2, −1, 2, 4, 7, 11 }

i think i got it now.... is the answer d?

Think of a set as a list of names (elements). You have two lists(sets) of names(elements) A and B. A intersect B is asking you, "what names (elements) are on BOTH lists(sets)?" In this case you have numbers instead of names.

@dmezzullo you are guessing. What number can you see in both A and B???? A: 2, 4,6, 8, 10, 12 B: −2, −1, 2, 4, 7, 11 |dw:1353339582910:dw|
