Question

Represent the following numbers as being members of set K: 2, 4, 2, 0, 6, 0, 10, 8

Can anyone help me on this, I do not understand what it is asking.

Answer 1

Hi, I can help you.

Answer 2

A mathematical set is a list of things, like a grocery list.

Answer 3

We typically give sets a single letter variable name.

Answer 4

And we use brackets to show the start and end of a set, with commas in between items.
For example: G = {cheese, milk, eggs, ceviche} is a set of my grocery list.

Answer 5

In math we often put numbers or variables in sets. For example S = {1, 2, 3, 4, e, i, pi}.

Answer 6

This has to do with real, natural, whole, and irrational numbers however.

Answer 7

In this example set S contains the numbers 1, 2, 3, and 4, pi and contains the variables e, i.

Answer 8

Correct

Answer 9

Here is another example of a set. S = {1,2,3}

Answer 10

This set contains the "natural" numbers 1,2,3.

Answer 11

So what you are saying is that the answer is just natural or whole numbers.

Answer 12

Not exactly, what I am saying is that a set can contain natural and/or whole numbers and/or rational numbers and/or irrational numbers and/or variables, etc.

Answer 13

We do not have to segregate numbers in sets.

Answer 14

S = {1,i,e,0,3/2}

Answer 15

One last thing that I forgot to mention about sets is that there are no duplicates.

Answer 16

This one has two duplicates, of the 2 and 0.

Answer 17

For example, if I want to put 0,0,0,1,2,3,4,4,4 into a set, S, it would like this S = {0,1,2,3,4}.

Answer 18

The duplicates are omitted in a set.

Answer 19

Okay, give your problem a shot now!

Answer 20

So the answer would be a simplier set of numbers that actually make a set that does not repeat itself.

Answer 21

Yes the answer would be a simpler list* of numbers that make a set that does not repeat itself (sets generally do not repeat themselves).

Answer 22

Okay, thanks.

Answer 23

So, what is your answer to this problem?

Answer 24

Represent the following numbers as being members of set K: 2, 4, 2, 0, 6, 0, 10, 8

Answer 25

{2, 4, 0, 6, 10, 8}

Answer 26

Correct

Answer 27

Generally we give our sets names.

Answer 28

Natural?

Answer 29

so set your set equal to the letter K, and we will call it "Set K".

Answer 30

okay, thank you.

Answer 31

Yes, your set contains natural numbers, but we do not name the set by its contents, rather we typically assign an arbitrary capital letter variable symbol equal to the set.

Answer 32

you're welcome

Answer 33

Oh, and, while it's not necessary. I like to order the numbers in my sets from least to greatest. It makes it easier to read, though it does not change the set.

Answer 34

Okay, I'll remember that in my math class at school monday. Thanks.

Answer 35

For example, S = {1,2,3} = {3,2,1} = {2,1,3} = {3,1,2}

Answer 36

Good good. Anything else I can help you with?

Answer 37

That'll be all, thanks though.
