Yes. a negative subtracting a negative equals a positive, therefore it would be 7+12 which would equal 19. your friend is correct.

Answer:

Yes.

Step-by-step explanation:

Yes it is correct.

When any bracket is opened by "-" sign then the sign inside the bracket changes.

Here,

→7-(-12)

→7+12

→19

In the above question the bracket is opened by "-' and the sign of 12 is also negative. So, -×- changes into +.
