I will help you evaluate the expression \([-28+(-8)]+12\)
\([-28+(-8)]+12\) | Brackets have equivalent priority to parentheses, so first evaluate \(-28+(-8)\)by realizing that adding a negative is equivalent to subtracting a positive. |
\([-28-8]+12\) | \(-28-8=-36\) |
\(-36+12\) | Now evaluate \(-36+12\) |
\(-24\) | |
Now, you are done!
