Evaluate (-28) + 38 + (-12). EXPLAIN YOUR ANSWER, I KNOW IT’S -2, BUT WHY? How do I get -2? I am asking you to explain how you solved, not tell me the sum. Thank you!

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...
