## jiehanthelearner Group Title How Do you write "A is the set of even whole numbers less than 12" in the notation builder? one year ago one year ago

1. ParthKohli Group Title

$\{\mbox{name of the set}:\mbox{condition}\}$

2. jiehanthelearner Group Title

can you write it for me? i still don't understand

3. ParthKohli Group Title

What do you call the set of even whole numbers?

4. jiehanthelearner Group Title

5. ParthKohli Group Title

Yes, I am helping ya. :-)

6. jiehanthelearner Group Title

Great,Thanks a bunch! you're very nice :D

7. jiehanthelearner Group Title

my problem is i don't know how to write it is it like this: A={x|x<...,x $\in$ ...} (note that "...." means i don't know what to put in there)

8. ParthKohli Group Title

$2\mathbb Z$is the set of even numbers.

9. ParthKohli Group Title

Where are you exactly stuck...?

10. jiehanthelearner Group Title

um,i'm stuck in the "..." part.. what should i write there?

11. AravindG Group Title

there you should write where the element belongs to

12. AravindG Group Title

and also include any condition if present

13. ParthKohli Group Title

$$x$$ is more than or equal to $$0$$ and less than or equal to $$12$$.

14. ParthKohli Group Title

For example, you can write the set of first ten natural numbers as:$\{x\in\mathbb N: x \le 10\}$

15. jiehanthelearner Group Title

i see! Tx you two! you guys are very nice for a newcomer like me,haha! well,Tx Again!

16. ParthKohli Group Title

Can you do it now? :-)

17. jiehanthelearner Group Title

hmm,kind off... well,Tx!

18. AravindG Group Title

for example if you are asked to write set of all even numbers you can write it as A={ x:x=2n ;n $$\in$$ N} N is set oof all natural numbers

*of

20. AravindG Group Title

yw :)

21. ParthKohli Group Title

Nah, I'd just use$A = \{x:x\in2\mathbb Z \}$And BTW, @AravindG, it should be the set of integers :-)

22. AravindG Group Title

I wanted to make it clear ..in schools we are first taught in that fashion ,then we play with it :) @ParthKohli

23. ParthKohli Group Title

But even numbers belong to the set of integers, not only N.

24. AravindG Group Title

*corrected :positive even numbers
