When adding integers of different signs, take the bigger number value (e.g 87 is bigger than 28) and subtract the smaller value from that. Then take the answer that you just got and put the sign of the bigger number value in front of the answer. (e.g 87 is bigger than 28, 87 - 28 = 59, the sign in front of the bigger # [87] was negative, 59 with a negative sign in front is negative 59)

Adding a negative number is the same as subtracting the positive value...
28 + -87 = 28 - 87 = -59
Your answer is...
-59
That's essentially 28 – 87 = 59. Or you could think of it as –87 + 28, or even (87 – 28) Ã (–1).
28 + (-87)
= (-59)

its a double sign so it automatically becomes a negative...
so its
28
- 87
but i swich it around so its
87
-28
and what you get there is your answer
and your anser is -59
28+-87
28-87
-59 answer
-59
