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!

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...
