$$\small{\text{
What integer $n$ satisfies $0\le n<9$ and $-1111\equiv n\pmod 9~?$
}}$$

 

$$\small{\text{
$-1111 \pmod 9 \equiv -4 \equiv -4+9 \equiv 5$
}}$$

n= 5

We don't mind all your questions Mellie, they are excellent questions I wish I had more time to do them and to learn from other people's answers too.  

That is my only complaint - time is always an enemy :)

 

Are you understanding the answers Mellie?  You can always quiz people on their answers, if you want to, you know.

I like seeing you answer questions on the forum too.  The more that you get involved the better that it is.  

That is what I think anyway :))
