Answer:
If the sign before the no. is same then they will get added and the resultant will have the same sign too.
Since before 28 and 12 , both of them have the negative sign , they will get added and the sign of their resultant will be negative too.
So , -28-12 = -40
Now, if the sign before the no.s are different then there will be subtraction, and the sign before the highest no. will be the sign of the resultant.
So,( -28)+38+(-12)
= -28+38-12
= -40+38
= -2
We know that 40> 38
sign before 40 is negative, therefore, their resultant i.e 2 will also get the negative sign
I hope this helps you...
