Answer:
-85
Explanation:
Given the mathematical expression:
![-18+(-67)](https://tex.z-dn.net/?f=-18%2B%28-67%29)
First, we recall the product of signs.
![+\times-=-](https://tex.z-dn.net/?f=%2B%5Ctimes-%3D-)
So, first, we open the bracket:
![-18+(-67)=-18-67](https://tex.z-dn.net/?f=-18%2B%28-67%29%3D-18-67)
We then simplify:
![=-85](https://tex.z-dn.net/?f=%3D-85)
The result is -85.
