If we subtract 6 from 3, we get -3.

Pretend these are dolars. So we have $3. We then pay someone 6$. How many dolars do you have left?

Well, we pay them the three we have, but then we owe them $3, because they still need $6 total.

We owe them 3 dolars, or we have -3 dolars.

 

Now let's just put a dot where -3 is on a number line.

 

Another way to look at this would be we started with 3 (blue dot) and we subtract 6, or move 6 to the left to get our red dot...which is -3

 

Either way you do it, -3 (which is the red dot) is your answer.
