Yes it's true. If you want to find the opposite just add (or subtract) the number you need to reach 0, in this case +7, and then add (or subtract) +7 again... the result is the opposite. Adding (or subtracting) 2 times itself passing from negative to positive and viceversa is the same of multiplying for -1, where 1 is the neutral number in multiplication.

Yes, that's true. The absolute value of a number is its distance from 
. With your example, we see that 
is 
away from 
. If we choose to think that 
is to the left of 
, then the opposite of 
is 
to the right of 
. That would be 
.
The multiplicative identity is 
. The opposite of the multiplicative identity is 
. Ergo multiplying by 
gives the opposite of a number.
