Answer:

In the expression -12 + 2 + 4 the "-" means "negative" and is firmly attached to the 12:

-12 + 2 + 4 = (-12) + 2 + 4 = (-10) + 4 = -6
---           ---------       ---------

Once the negative is attached to the 12, the rest is done by going left to right since the two + are of equal priority.

In the priority chart, exponent is the highest priority of all. This means that it will be done before anything else. Remember that "^" means "raised to the power of".
