anonymous · Answer

list what ?

anonymous · Answer

do you know all the natural numbers that are less then 11?

anonymous · Answer

no

anonymous · Answer

okay natural numbers are numbers you can use to count something like 1,2,3,4

zzr0ck3r · Answer

$\{n \in \mathbb{N} \mid n< 11\}$

anonymous · Answer

ok so 1 to infinity right ?

anonymous · Answer

Yes

anonymous · Answer

and they cant be negative either. okay now do you know what set-builder notation is or how to right it?

anonymous · Answer

no i know what a natural number is now

anonymous · Answer

okay so this is set-builder notation:     {p|p<0}

anonymous · Answer

so p is any thing that is less than 11 and is a natural number

anonymous · Answer

so it's {p|p<0} ?

anonymous · Answer

it is greater than 0 but less than 11 so 11<0

anonymous · Answer

so p equals p=11<0 or {p|11<0}

anonymous · Answer

the second one is set-builder notation.

anonymous · Answer

ok, so the answer is {p|11<0} ?

anonymous · Answer

wait nooooo, we have to say its a natural number! sorry!

anonymous · Answer

huh ?

anonymous · Answer

since that one only states that is can be any number not only natural numbers

anonymous · Answer

so im pretty sure it would be like this:   p={x|x is a natural number > 11}

anonymous · Answer

this states that p can be any number less than 11 as long as it is a natural number. so 1,2,3,4,5,6,7,8,9,10
